Test Code HPVHL Human Papillomavirus (HPV) High/Low Risk, DNA In Situ Hybridization

Additional Testing Requirements

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


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.
