Human Papillomavirus (HPV), High-Risk, DNA In Situ Hybridization
Detection of human papillomavirus DNA from high-risk genotypes (16, 18, 31, 33 and 51)
Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
Human papillomavirus (HPV) high risk E6/E7 will be performed at the discretion of the Mayo pathologist.
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 (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.
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.
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 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. If this test is negative, a more sensitive test, 62886 / Human Papillomavirus (HPV) High Risk E6/E7, RNA In Situ Hybridization, could be performed if clinically indicated.
