The Viper LT™ is a benchtop molecular platform that automates DNA extraction, RT-PCR amplification, detection and result reporting — minimising manual intervention. Paired with the Onclarity™ HPV Assay, it delivers genotyping results for 14 high-risk HPV types, with individual identification of 6 types, from the same SurePath™ vial used for liquid-based cytology — one sample, two tests.
Onclarity™ is the only HPV assay that provides extended genotyping for all 14 high-risk types in a single test run. Primers and probes are designed to target the HPV E6/E7 oncogene region — the most clinically significant region for cancer risk assessment — significantly improving viral detection sensitivity and reducing the risk of missed detection due to nucleic acid deletions or mutations.
The assay uses 15 different probes, each labelled with one of four fluorescent dyes, preventing suppression of low-concentration targets by high-concentration targets in mixed infections. Cross-reactivity testing has confirmed no interference with multiple bacteria, fungi, viruses or low-risk HPV types. Common vaginal interfering substances (medications, lubricants, hormones, blood) do not affect results.
