Hpv mrna e6 e7 detected what does that mean

A detected result indicates the presence of high-risk HPV E6E7 mRNA and. Some of these are commercially available.

Tests that meet these criteria include tests that focus on p16Ki-67 and E6 and E7 which are HPV oncoproteins.

Hpv mrna e6 e7 detected what does that mean. My pap results shows HPV mRNA E6E7. It also says epithelial cell abnormality low grade squamous intraepithelial lesion LSIL. What does this mean.

I also already had a colonoscopy last year and the results were CIN1. Dont worry about the E6 E7. That just refers to what the test is detecting that then points to a detection of the virus strains listed afterwards.

Youll have to do further research on this assay to understand how they differentiate between the different strains because I dont feel like doing that right now. However the results show that you have tested positive for at least one of those strains. You should also Google.

HPV E6E7 mRNA testing for high-risk types seems to correlate better with the severity of the lesion compared with HPV DNA testing and is a potential marker for the identification of women at risk of developing cervical carcinoma. Commercial assays for simultaneous genotyping and detection of E6E7 mRNA from the five most common high-risk HPV types are now available and require further. Most published studies referred to the detection HPV mRNA E6-E7 are related to cervical tissue disease and management.

There are several published works that mention the detection of HPV 16 E6 E7 transcripts in metastatic lymph node 25-27 they have applied RT-PCR techniques in fixed samples. In all the studies have indicated that the detection of viral mRNAS is a more sensitive indicator than. The E6 and E7 mRNA detection assay PreTect HPV-Proofer based on real-time multiplex NASBA as well as a separate real-time multiplex NASBA assay were used to study E6 and E7 mRNA expression from HPV types 16 18 31 33 35 45 52 and 58 which are the most prevalent high-risk HPV types in Europe and North America.

The results were compared to those of consensus. A positive HPV E6E7 mRNA testing result suggested the women with ASCUS or LSIL Pap smear was in a truly dangerous position which is an adverse prognostic factor. It suggested that cervical lesions stay in a progressing status and these women should be referred for colposcopy and strengthen follow.

HPV E6E7 mRNA testing for high-risk types seems to correlate better with the severity of the lesion compared with HPV DNA testing and is a potential marker for. The E6E7 mRNA test showed a higher prevalence of E6 and E7 transcripts in patients with higher-grade lesions. The results of this study suggest that the HPV genotype determination and E6E7 mRNA detection would find an important application for management of HPV positive women.

A total of 165 endocervical samples harboring HPV 16 andor 18 DNA were tested with NucliSENS-EasyQ HPV E6E7-mRNA-assay Biomerieux Marcy lEtoile France. Women with cytological alterations were referred to colposcopy n 111. Moderate-grade cervical intraepithelial neoplasia or worse was diagnosed in 258 of women presenting atypical squamous cells of undetermined.

The genome organization and protein structure of E6 and E7 have been discussed followed by their mechanism to establish the six major cancer hallmarks in cervical tissues for tumor propagation. The later section of this review article deals with the different modes of therapeutics which functions by deregulating E6 and E7 activity. Since E6 and E7 are the biomarkers of a cervical cancer cell and are.

What does the presence of mrna E6E7 mean. After 2 negative paps it returned with 14 high risk types and the presence of E6E7. But a WNL pap result.

What does this mean. DNA-based human papillomavirus HPV assays show high sensitivity but poor specificity in detecting high-grade cervical lesions. Assays detecting mRNA of the oncoproteins E6 and E7 show higher specificity but lack either detection of all high-risk HPV genotypes or the capacity to specify the detected genotypes.

HPV Test Result. An HPV test result can be positive or negative. A negative HPV test means you do not have an HPV type that is linked to cervical cancer.

Your doctor may tell you that you can wait five years for your next screening test. A positive HPV test means you do have an HPV type that may be linked to cervical cancer. This does not mean you have cervical cancer now.

High-risk HPV E6E7 mRNA a level of HPV mRNA below the detection limit of the assay or presence of a genotype other than those listed above. It suggests a low risk of cervical cancer. A detected result indicates the presence of high-risk HPV E6E7 mRNA and.

About the presence of infection and the viral type the detection of E6 and E7 mRNA identifies HPV genotypes most frequently found in cervical cancer 16 18 31 33 and 45 and is also indicative of the expression of oncoproteins E6 and E7 of these viruses which have been directly associated with malignant transformation. Likewise HPV test results can either be positive meaning that a patients cervical cells are infected with one or more of a group of high-risk HPV types which is what most commercially available HPV tests detect or negative indicating that none of the high-risk HPV types were found. Several HPV tests are specific for HPV16 and HPV18the types that cause most cervical cancers.

Tests that meet these criteria include tests that focus on p16Ki-67 and E6 and E7 which are HPV oncoproteins. Some of these are commercially available. Persistent infection with human papillomavirus HPV is the principal cause of cervical cancer and its precursor cervical intraepithelial neoplasia CIN1-3 The presence of HPV has been implicated in more than 99 of cervical cancers worldwide.

HPV is a small nonenveloped double-stranded DNA virus with a genome of approximately 8000 nucleotides. There are more than 118 different types of HPV.
