| Additional information | Sufficient cellularity in the submitted sample is a requirement for accurate results. Low cellularity may produce false negative results. Clinical utility, interferences, references, etc.: HPV DNA typing should be used in the management of women with aytpical squamous cells of undetermined significance. This test detects the HPV high-risk types. There are 13 gentypes/strains which are associated with HSIL and invasive cancer: 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 68. The assay does not differentiate among the HPV genotype/strains and is qualitative. Sensitivity and specificity vary depending upon the PAP smear result.

Some low-risk types such as HPV6 and HPV42 cross react in this assay and high concentrations (> 4 ng/mL) of these low-risk types may produce a positive result in this assay. |
