Test 60483 :
Human Papillomavirus (HPV), High-Risk, DNA In Situ Hybridization

Clinical Information Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test

Persistent infections with high risk human papillomavirus (HPV) genotypes 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.

Useful For Suggests clinical disorders or settings where the test may be helpful

Detection of human papillomavirus DNA from high-risk genotypes in paraffin-embedded human tissue

Interpretation Provides information to assist in interpretation of the test results

This test will be processed as a special procedure. If additional interpretation/analysis is needed, order 70012 / Pathology Consultation along with this test.

Cautions Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

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 (OPSCC). Following a negative DNA ISH result, a more sensitive in situ RNA test could be performed, if clinically indicated. The RNA test is only available in the context of a pathology consultation (70012 / Pathology Consultation).

Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.

Results are reported as positive or negative for types 16, 18, 31, 33, and 51.

If additional interpretation/analysis is needed, please request 70012 / Pathology Consultation along with this test.
