Test Code DHPVB Human Papillomavirus (HPV) Types 18, 31, 33, and 35, Droplet Digital PCR, Blood


Ordering Guidance


This test should be ordered to monitor circulating cell free DNA for the high-risk human papillomavirus (HPV)-18, -31, -33 or -35 genotypes in patients with a previous diagnosis. If the intent of the order is a pre-diagnostic screen for which the genotype is not previously known, order DHPVR / Human Papillomavirus (HPV) Type 16 with Type 18, 31, 33, and 35 Reflex, Droplet Digital PCR, Blood which can detect and quantify circulating cell free DNA from 5 high-risk human papillomavirus genotypes: HPV-16, -18, -31, -33 and -35.

 

For routine cervical cancer screening, order VHPV / Human Papillomavirus (HPV) Vaginal Detection with Genotyping for High-Risk Types by PCR.
