26491 Human Papillomavirus (HPV), High-Risk, DNA In Situ Hybridization (HPVHR)

Human Papillomavirus (HPV), High-Risk, DNA In Situ Hybridization (HPVHR)
Test Code: HPVHRSO
Synonyms/Keywords

​HPV (Human Papillomavirus), HPVHR, GPHPVHRISH, ISHPVFAM16ISH, ISNEGHPVISH, ISDNAHPVISH

Test Components

The probe set used in this human papillomavirus (HPV) DNA in situ hybridization (ISH) test cannot detect all potential HPV serotypes that are associated with oropharyngeal squamous cell carcinoma. If this test is negative, a more sensitive test, Human Papillomavirus (HPV) High Risk E6/E7 RNA In Situ Hybridization, could be performed and reported if clinically indicated but will not be billed separately.​

Useful For

​Detection of human papillomavirus DNA from high-risk genotypes (16, 18, 31, 33, and 51)

Test Information

​Persistent infections with high-risk human papillomavirus (HPV) genotypes (16, 18, 31, 33, and 51) are associated with cervical, vaginal, vulvar, and head and neck malignancies. Patients with HPV-related oropharyngeal squamous cell carcinoma (OPSCC) have shown better disease-specific survival and overall survival when compared to HPV-negative cases of OPSCC.

Interpretation

​This test, when not accompanied by a pathology consultation request, will be answered as either positive or negative. If additional interpretation or analysis is needed, request PATHC / Pathology Consultation along with this test.
