One is to start screening at a slightly older age, and the other is to preferentially recommend a type of screening test called an HPV test. ACS recommends cervical Gel Papillor screening with an HPV test alone every 5 years for everyone with a cervix from age 25 until age (*A primary HPV test is an HPV test that is done by itself for screening. The US Food and Drug Administration has approved certain tests to be primary HPV tests.) A Pap test is used to find cell changes or abnormal cells in the cervix. In Ireland, a national cervical Gel Papillor screening programme and HPV vaccination were recently launched; HPV testing is currently being integrated into the screening programme. Women’s views on the transformation of cervical Gel Papillor prevention have been relatively little investigated. Women having primary HPV screening must be sent the screening leaflet ‘NHS Screening: Helping you decide’ and a copy of the leaflet for primary HPV screening together with their invitation letter.

The application of lean principles to transport processes is common, for example in the use of colour coded transport boxes and specimen bags. A clinical study conducted among more thanwomen in the Netherlands found that HPV testing done on cervical samples collected by women themselves had similar accuracy to that of clinician-collected samples for the detection of Screening hpv tara to severely abnormal cervical cells. When a provider performs colposcopy, he or she will usually remove cells or tissues from one or more concerning areas for examination under a microscope, a procedure called a biopsy. Media Contacts.
To ensure that future cervical Gel Papillor prevention strategies will be acceptable to women, Screening hpv tara thought will have to be given to information provision and education. PCSE will need to: validate the cohort selection with the SIT ensure that the flag defining that primary HPV screening is being utilised is switched on, which will ensure the correct letters and leaflets are sent to the Screening hpv tara cohort ensure that women receive the correct primary HPV Screening hpv tara invitation letters for the screening technology in use, commencing approximately 6 weeks prior to transfer to primary HPV screening at the laboratory ensure that all of the relevant parameters are set Screening hpv tara the women if a new cohort of the population is defined, thus ensuring appropriate and timely communication ensure the appropriate delivery times are defined on the parameters which drive the VSA15 turnaround statistics, once switchover takes place But if you have many treatments and biopsies, which can happen with more frequent screening, the risk of pre-term labor and low birth weight babies can go up.

This is a test carried out on the sample of cells we take. during cervical screening. It makes no difference to what happens at your screening appointment. HPV testing is used for cervical Gel Papillor screening.
It is more sensitive and effective than other screening tests, and can accurately identify women at high risk of developing cervical Gel Papillor. There are several HPV testing products available. The primary HPV screening tool, developed by Roche and performed on its cobas molecular platform, was approved for FDA use in early This screening method looks for presence of HPV nucleic acid in patients 25 years or older. Fourteen subtypes of high-risk HPV are detected.

All samples taken by sample takers in training Screening hpv tara be clearly identified to the laboratory. A joint statement Screenig by the American College of Obstetricians and Gynecologists, American Society for Colposcopy and Cervical Pathology, and the Society of Gynecologic Oncology noted that the updated guidelines are largely in line with their clinical guidance, with some differences in the details.

Women part way through follow up for cervical Gel Papillor who still have a cervix should be managed by hrHPV testing at their Scrsening test and not continue with cytology-based follow up. Martin, C. This Collection.
Overall, both platforms were comparable and viable for a HPV primary screening population however, both would require adequate triage testing of HPV positive women. Cytology will likely be the initial triage test for HPV positive women. An alternative approach to triaging women using methylation markers was assessed in this study. These individual methylation markers were investigated in several different and novel combinations. Cut-off points were determined for each individual methylation marker, as well as for the Total and Paired Methylation Score by ROC curve analysis.
From this, the Total Methylation Score had a sensitivity and specificity of The Paired Methylation Score performed well with a sensitivity and specificity of Of the three individual methylation markers, hsa-mir had the highest individual performance with a sensitivity and specificity of These three methylation approaches were brought forward to be assessed in a HPV positive triage population.
When applied to the HPV positive population, the Paired Methylation Score had the best performance with a sensitivity of Referral rates for each of the three methylation approaches were comparable to the referral rates of cytology None of the methylation approaches with or without HPV genotyping were able to safely refer women back to the routine recall population. The use of methylation testing shows great potential in the triage of HPV positive women. Advisor: Martin, Cara. Publisher: Trinity College Dublin. School of Medicine. Discipline of Histopathology.
Centralisation of screening laboratory services will lead to laboratories serving a larger number of GP practices, colposcopy clinics, sexual health services and histology laboratories, with many residing in different trusts.
Screening laboratories will need to maintain strong links with all of these services to ensure continuity and provision of a high-quality service. This includes the timely referral of women using direct referral, electronic transfer of results to Primary Care Support England PCSE , IT links enabling the screening laboratory to look up colposcopy outcomes or histology results and representation at colposcopy multidisciplinary team MDT meetings.
The role of the cervical screening provider leads is vital in bringing these aspects of the programme together. NHS England has put a resilience plan in place which aims to maintain the delivery of a high-quality service to women during the transition to primary HPV screening.
This is dependent on laboratories meeting defined quality criteria and having a robust plan in place to ensure primary HPV testing is implemented in accordance with this guidance and continues to meet quality standards.
Providers participating in the resilience process will continue to deliver primary HPV screening in the interim until the commissioned centralised laboratory services begin. All elements of local cervical screening programmes will need to be engaged well in advance of implementation. Local cervical screening programme boards will be central in leading this process and addressing the various work streams required. The cervical screening programme offers primary hrHPV testing to women as an improvement to the screening service.
It is not possible for women to request a cytology test instead.
Once this is confirmed, her consent to primary hrHPV testing and cytology triage where indicated is implied by the fact that she attends and accepts the procedure. The introduction of primary HPV screening requires standard screening invitation and results letters. The NHSCSP has produced templates for the screening invitation and result letters associated with each type of result. Where second reminder invitations are sent by GPs , the text of these letters must be revised accordingly. These leaflets must be sent with all screening invitations for a period of 6 weeks before the introduction of primary HPV screening protocols for that population in the laboratory. This will help to ensure that women attending for screening receive the correct information in time for the switch from cytology to hrHPV testing.
Samples should continue to be taken in the same way in accordance with programme guidance.
Providers of screening laboratory services to the NHS Cervical Screening Programme are responsible for providing systems to transport screening samples from primary care into the laboratory. Sample logistics are an important consideration for the implementation of primary HPV screening. The centralisation of cervical screening including hrHPV testing and cervical cytology means many samples will need to be transported over greater distances to reach the screening laboratory, whilst still providing an efficient and timely service for women.
In addition, cervical screening laboratories have traditionally supplied GP practices with liquid based cytology LBC consumables. Samples must be transported from primary care providers to the centralised screening laboratory in a timely manner, enabling women to receive their screening results in line with the day turnaround time core programme standard.
The transportation of samples must comply with the guidance detailed in the Recommended code of practice for cytology laboratories participating in the UK cervical screening programmes and relevant clauses of ISO , which requires a system to track samples from source through to receipt in the laboratory.
Where a centralised screening laboratory uses a third party for example the local NHS trust to receive and sort samples from local GPs for onward transportation, service level agreements must be in place detailing the requirements of the service. The application of lean principles to transport processes is common, for example in the use of colour coded transport boxes and specimen bags. Commissioners and providers may want to explore opportunities to speed up transportation and improve the tracking of samples.
These include: LBC consumables must be stored and distributed in accordance with conditions specified by the manufacturer and relevant clauses of ISO Where a centralised screening laboratory uses a third party to distribute consumables, there must be a service level agreement in place detailing the requirements of the service.
Centralised screening laboratories will require appropriate and sufficient storage capacity to accommodate large numbers of LBC vials received for screening. Once all testing is complete and the results have been reported, LBC samples can be discarded according to the normal laboratory retention, storage and disposal procedures. However, where cytology slides are produced following primary HPV screening, they must be stored for 10 years. The hrHPV testing service will be co-located on the same site with cervical cytology to provide a single seamless service.
Electronic download of hrHPV test results into the LIMS cytology screening record is essential and the cytology component of the screening service will be responsible for the issuing of all screening results, including those where the result is hrHPV negative.
On receipt, all screening samples must be booked onto the cytology LIMS system that will produce the screening report. The hrHPV test will be the initial test performed on all cervical screening samples. Those testing hrHPV negative will require no further testing excepting samples taken by novice samples takers see section Those testing hrHPV unavailable should be repeated in no less than 3 months, unless this is the second consecutive hrHPV unavailable or inadequate cytology result when a referral to colposcopy will be made see section Cytology slides will undergo a full cytological examination as well as internal quality control by rapid preview or rapid review.
Cytology results must be reported together with the hrHPV test results in a combined screening report from the cytology laboratory. The requirement for cytology screeners across the programme will reduce as fewer samples require cytology under the new protocols. The requirement for checking and abnormal reporting is not expected to reduce in the initial years following implementation. In the pilots of primary HPV screening approximately one third range Details of the acceptable tests including methods to be employed, sample requirements, platforms and permitted modifications to protocols detailed in kit inserts are published on GOV.
Laboratories providing NHS cervical screening services must use one of 2 LBC systems that are currently approved for use in the programme. This system has not been evaluated for use in a setting where the primary screening test is an hrHPV test and is not currently approved for use in clinical practice in the NHSCSP.
Service leads in the form of a lead virologist and lead scientist for hrHPV testing are required. These individuals will have specific responsibility for clinical governance and are directly accountable for the quality of their own work and that of their departmental teams. Cervical cytology laboratories must have an SLA s in place for virology services. This can vary depending on where the hrHPV test is carried out whether within the cytology department or a virology department.
Appropriate consultant virologist support must be provided to a cytology service performing hrHPV testing and be available when required. A consultant virologist or lead scientist appointed to provide external advisory services to a cytology laboratory must hold an honorary contract with the host provider. All laboratories providing hrHPV testing must participate and maintain adequate performance in an ISO accredited external quality assurance scheme.
Further to this, all laboratories providing hrHPV testing should refer to the guidance on laboratory quality control and assurance for human papillomavirus testing. Criteria will be established for the use of the unavailable hrHPV test reporting code to make sure there is consistent reporting across laboratories.
The internal control signal in samples serves to confirm that each sample has sufficient cell input for accurate hrHPV detection, was processed correctly, and to indicate whether inhibitors of amplification are present. Test run controls include a positive and negative control provided with the kit and one of each is required with every run. The negative control serves to verify that hrHPV contamination did not occur during the sample preparation and set-up of the amplification reaction.
HPV platforms that have sample internal controls report an invalid result when the sample internal control for example β-globin result is negative or invalid in hrHPV negative samples. A repeat test is performed starting with sample preparation. If still no valid result the sample will be reported as HPV -U. Where the sample internal control is negative or invalid an hrHPV positive result remains valid and will be reported as such. These should be reported as HPV positive. HPV platforms will report error codes or flags due to insufficient volume or clot detected as failed samples. Insufficient samples will be reported as HPV -U.
A repeat test is performed on clot detected samples starting with sample preparation. If the sample fails again the sample will be reported as HPV -U. When samples cannot be reported due to failure of test run controls, or fail due to instrumentation errors and failures, a flag or error code is generated to alert the user to the problem.
The problem should be addressed and once resolved the samples can be re-tested. If subsequently no result is obtained due to insufficient sample, this should be reported as HPV -U as above. Subsequent cytology should be reported as inadequate unless abnormal cells are found. They must not be reported as HPV -U.
If hrHPV positive, cytology triage will be performed which will be reported as inadequate unless abnormal cells are identified. These samples should be rejected. Subsequent cytology should be reported. Subsequent cytology can be reported providing there is sufficient residual sample for processing. If there is insufficient volume it should be reported as cytology inadequate.
All staff must be trained and competent to meet the requirements of cervical screening based on primary hrHPV testing. Specific training requirements are outlined below. Local training will be required to cover changes to processes required for primary HPV screening, including but not limited to the ordering and supply of sample taking materials, sample transport, sample processing in laboratories and use of IT platforms.
Engaging primary care is crucial if primary hrHPV testing is to be successfully implemented. Sample takers have an important role in ensuring that women understand the concept of hrHPV testing and the results of their screen. It may also be a useful resource for colposcopy staff as women often have questions about hrHPV testing on attendance at colposcopy.
It is recommended that all sample takers complete the e-learning, which includes a question and answer section and certificate of completion, prior to the sample taker participating in screening with primary hrHPV testing.
The eLearning resource is hosted on the eLearning for Health website. Completion of the online training can be recorded on the local sample taker register, according to local requirements. Sample takers may also require system specific training if the LBC vial type used changes with the move to the centralised laboratory service. Sample taker training must continue to be offered to staff in areas and practices which have converted to primary HPV screening, including assessing novice sample taker competency within the programme guidance.
All samples taken by sample takers in training must be clearly identified to the laboratory.
All samples with a valid hrHPV result must have a cytology sample prepared and reported, irrespective of whether the HPV result is positive or negative. Samples which give an unreliable hrHPV result do not have a cytology slide prepared and must be repeated after a period of not less than 3 months and for the purposes of sample taker training recorded as unsatisfactory. All cytology and hrHPV test results must be logged on the laboratory IT system to give a full record of the test result, and so that feedback on cytology adequacy can be given to both sample takers in training and course organisers in the usual way.
Cytology slide review in addition to hrHPV testing of samples may result in a combination of cytology and hrHPV test results which is not recognised in the primary HPV screening protocol.
For example, a hrHPV negative result in combination with high grade abnormal cytology must be reported using the appropriate HPV triage code combination, to make sure that the woman is referred to colposcopy.
A summary of test result and action code combinations which cannot be recorded as primary HPV screening tests, in particular, those which must be identified and recorded as HPV triage tests, is given below. In these circumstances, the inadequate cytology result must be disregarded for the purposes of recall. The quality of the sample must still be fed back to the sample taker with an explanation that the sample does not require repeating in 3 months and detailing the required management.
If following a hrHPV negative result the cytology sample is found to be acellular casting doubt over the validity of the hrHPV test result and a decision is made to repeat the hrHPV test in 3 months, this must be reported using code combination XUR, in accordance with section Training on a new HPV platform must be delivered by the supplier to an appropriate core of staff who can then deliver cascade training to existing and new staff.
SQAS must be provided with evidence that: If a laboratory decides to adopt more than one hrHPV testing method, staff must be trained to required level of competence in each of the tests used. All staff involved in the screening and reporting of cytology samples following primary hrHPV testing must have up-to-date knowledge of the HPV screening pathway.
Training courses will be provided by programme approved cervical cytology training centres.
All colposcopists receiving primary hrHPV screening referrals are expected to complete training and undertake the relevant study. A national colposcopy e-learning module on primary HPV screening has been developed, which is hosted on the eLearning for Health website. The reconfiguration of screening laboratory services associated with implementing primary HPV screening will impact significantly on the role of the CSPL. The scale and complexity of the role will increase in providers with large screening laboratories referring women to multiple external colposcopy units, and the audit of invasive Gel Papillors across separate providers will require extra coordination.
There will also still be a need for CSPLs in those providers still providing parts of the cervical screening pathway but where there is no longer a cervical cytology laboratory.
The role of the CSPL will, therefore, be vital in ensuring that links are maintained between all elements of the local programme and that individual components of the service function together to provide the best possible service and outcomes for women. Guidance has been developed to support the requirements of the CSPL role. CSPLs new to the role and those requiring further development should attend programme approved training. The lines of communication should be maintained throughout the transition period. Laboratories and screening and immunisation teams need to notify PCSE of:
The laboratory system must have the functionality to provide the primary HPV screening flag as follows, for every individual test noting the exceptional combinations associated with novice sample takers. Technical advice for the laboratory system or middleware suppliers is available on request from Exeter. The laboratory LIMS must be able to support this new result code.
Cytology result codes X No cytology result 0? Action codes A routine recall R early repeat in 3, 12 or 36 months S suspend from recall. It will not be formally rejected by the system and therefore no automatic warning or a system-generated error message will be provided to the laboratory when the test result is recorded.
The laboratory cannot, therefore, specify a non-standard recall interval for any woman. There is no override facility for individual cases beyond those described below and so it is not possible to recall women at shorter or longer intervals than those defined in the protocol. Where there is uncertainty over the quality of the sample, these should be rejected, or accepted and reported in accordance with guidance detailed in section Samples accepted but requiring a repeat sample in 3 months must be coded as XUR or 19R as appropriate.
Code combination X0R must not be used for tests requiring 3-month repeat as it will be implemented as the default recall interval of 36 months.
There are 2 valid recall intervals applicable to tests coded X0R, 29R and 09R. In each case, the woman could require recall in either 12 or 36 months. A default interval will apply to these results although an allowable alternative can be provided by the laboratory which will override the default value. The defaults and allowable override values are: Test results will be rejected by the call or recall system if they are flagged as primary hrHPV tests and:
It is recommended that the laboratory LIMS incorporates basic validation to prevent the issue of these results where possible. Women will be called for screening from age Women are currently screened every 3 years between the ages of The UKNSC is considering the evidence to support extending screening intervals for all women in the screening age range.
Women recalled for a repeat screen at 12 months due to being hrHPV positive with negative cytology at their preceding test will have a repeat hrHPV test. All hrHPV positive women will have cytology triage performed on their sample.
Those with abnormal cytology will be referred to colposcopy. Women with negative cytology will be recalled for a further 12 month repeat test 24 months from the initial screen. Women returning for a second repeat test, 24 months since the initial screening test, will receive an hrHPV test. Cytology performed here defines the urgency of referral required and assists the colposcopist.
A gynaecological referral must be made for women with a cytology result of? These women will be followed up for their hrHPV positive result in the same way as women with negative cytology by repeat screening at 12 and 24 months. When the hrHPV test result is unavailable or cytology is inadequate at any screening episode in the pathway, the sample will be repeated in no less than 3 months. Women who have an inadequate cytology test at the 24 month repeat test are an exception and will be referred to colposcopy.
Women with 2 consecutive hrHPV unavailable or cytology inadequate screening tests in any combination will be referred to colposcopy. Cytology will not be performed on any sample where an hrHPV positive result has not been obtained exception in the case of novice sample takers see section This includes samples from women attending for 12 month repeat tests. Guidance on the criteria for assessing cytological adequacy will be published shortly on GOV.
Women recently treated for cervical intraepithelial neoplasia CIN or cervical glandular intraepithelial neoplasia CGIN prior to the implementation of HPV primary screening should be managed according to the colposcopy management recommendations for the implementation of primary hrHPV screening see section 14 and appendix 2.
Follow up differs slightly to the test of cure protocols used previously, most notably in that cytology is not required for hrHPV negative women. Women being followed up for untreated CIN1 should also be managed by hrHPV testing according to the colposcopy management recommendations for the implementation of hrHPV primary screening see section Women who have completed follow up protocols when primary hrHPV testing is implemented and are returning for their next test 36 months later will begin a new screening episode, according to the primary hrHPV screening protocol algorithm.
Women part way through follow up for cervical Gel Papillor who still have a cervix should be managed by hrHPV testing at their next test and not continue with cytology-based follow up.
HIV positive women within the screening age range are eligible to be screened annually and should be invited for screening using hrHPV as the primary test rather than cytology. The management of these women will follow the protocols for primary hrHPV testing in all other aspects other than frequency of screening. At the current time, these women remain in the programme according to screening protocols. Laboratories providing primary hrHPV testing and cytology triage to the NHS screening programme will be required to use a system of direct referral of women to colposcopy. Direct referral reduces anxiety for women by speeding up the patient journey and facilitates improved management of clinics, reducing waiting lists and non-attender rates.
An efficient system needs to be in place to correctly identify the appropriate colposcopy clinic to send the referral and ensure it is received.
Women with an intact cervix who have received radiotherapy of the pelvic region for example for anal, cervical, low colorectal and vaginal Gel Papillors which means that an adequate sample cannot be obtained, are not eligible for cervical screening using primary hrHPV testing. They can be ceased from the programme. For further information see guidance for ceasing women from the programme. Where a woman has defaulted colposcopy following high grade abnormalities and attends for screening 12 months later through the failsafe process, she should be re-referred to colposcopy even if her result is hrHPV negative. If, however, she has defaulted colposcopy following low grade abnormalities she does not warrant re-referral to colposcopy if her result if hrHPV negative; her management will follow the usual national protocol.
Women who have a private screening test remain eligible for NHS testing at appropriate intervals subject to a minimum of 3 months between samples. Primary screening tests taken under private arrangements are managed in the following ways: Women who are due or overdue for their NHS test should be encouraged to take up their screening following a private HPV positive result. The recommended management pathways and follow up for women being referred to colposcopy following abnormal results from primary HPV screening are summarised in Appendix 2. The implementation of primary HPV screening pathways leads to an increased number of colposcopy referrals. This compared to 3. The impact of recalling women at 12 and 24 months following HPV positive results with negative cytology amounted to an extra 1.
The first full school-based cohort of vaccinated women entering the programme in will impact this.
Women with inadequate colposcopy examination are managed on the results of their referral screening test. Those with borderline changes in endocervical cells and high-grade dyskaryosis or worse cytology will be offered a large loop excision of the transformation zone LLETZ procedure. Women with no biopsy taken, a biopsy showing no CIN , or where there was no colposcopic impression of CIN will be recalled in 36 months if their referral cytology results were negative, borderline changes in squamous cells or low-grade dyskaryosis.
Women referred with borderline changes in endocervical cells and high-grade dyskaryosis or worse should have their case discussed and management agreed at the colposcopy multidisciplinary team meeting within 2 months. If CIN is confirmed on biopsy or there is colposcopic impression of CIN1 without a biopsy, the woman will be managed according to the same protocols as women with an abnormal colposcopic appearance, detailed in the following sections.
The management recommendation for women who have a colposcopic appearance consistent with CIN1 or CIN1 confirmed on biopsy is recall for screening in primary care in 12 months with hrHPV testing.
HPV and HPV Testing
The human papillomavirus HPV test detects the presence of human papillomavirus, a virus that can lead to the development of genital warts, abnormal cervical cells or cervical Screening hpv tara. However, men can be infected with HPV and pass the virus to their sex partners. The Screening hpv tara test is Screening hpv tara screening test for cervical Gel Papillor, but the test doesn’t tell you whether you have Gel Papillor. Instead, the test detects the presence of HPVthe virus that causes cervical Gel Papillor, in your system. Certain types of HPV — including types 16 and 18 — increase your cervical Gel Papillor risk.
Knowing whether you have a type of HPV that puts you at high risk of cervical Gel Papillor means that you and your doctor can better decide on the next steps in your health care. Those steps might include follow-up monitoring, further testing or treatment of abnormal cells.
