Test ID: 80172    
Human Papillomavirus (HPV) Typing In Situ DNA Hybridization

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

The detection of specific human papillomavirus DNA types in paraffin-embedded human tissue. These are type 6/11, and/or 16/18/31/33/35/39/45/51/52/56/58/66.

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

Many human papillomavirus (HPV)-induced lesions are benign presenting as warts or condylomas. However, certain HPV types have been strongly associated with risk of development of cervical, vaginal, and vulvar malignancy.

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 6, 11, and/or types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, and 66.

If additional interpretation/analysis is needed, please request 5439 Surgical Pathology Consultation along with this test.

Interpretation Provides information to assist in interpretation of the test results

Human papillomavirus (HPV) types 6 and 11 are the predominant viruses associated with condyloma acuminata (genital warts). The condition usually remains benign.

 

HPV types 16/18/31/33/35/39/45/51/52/56/58/66 frequently are found in CIN III (severe dysplasias and carcinoma in situ) and cervical cancer.

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

This assay has been designed for use with buffered, formalin-fixed, paraffin-embedded human tissue. It has not been tested extensively with frozen tissue and is not qualified for use with other fixatives.

 

A negative result does not exclude the presence of human papillomavirus (HPV) infection.

 

Failure to detect target DNA may be a result of such factors as improper sampling, fixation, and/or processing of the specimen, or the presence of target DNA at levels below the sensitivity of this assay.

 

Some tissues with morphological changes indicative of HPV infection may not be reactive with the HPV probes currently available.

 

Other HPV types may appear in anogenital lesions but are not detectable with the probes provided using the hybridization conditions employed in this assay.

 

Not useful for the detection of HPV DNA of any other types than type 6/11, 16/18/31/33/35/39/45/51/52/56/58/66.
