PhenoSense, offered as a single test or in the combination test, PhenoSense GT®, represents cutting-edge resistance testing technology. PhenoSense is the only resistance test that uses clinical cutoff values, and can measure hypersusceptibility and replication capacity. In addition, the PhenoSense report makes resistance data easy to apply to treatment selection, with a fold-change bar graph and drug susceptibility curve for each drug that demonstrates the performance of a patient's virus next to a drug-susceptible wild-type reference virus. PhenoSense is a valuable therapy guidance tool, and is the most commonly used phenotypic HIV drug resistance test performed today.

Technical Feature	Advantage to User
Provides quantitative assessment of susceptibility	Allows provider to select optimal regimen even when few good choices remain by evaluating degree of resistance
Cutoffs based on clinical response data from specific clinical trials	Cutoffs accurately reflect the incremental impact of a single drug on a regimen
Only assay that measures hypersusceptibility and replication capacity	Use these unique viral measures to develop alternative treatment strategies
More precise and sensitive than competing phenotypes	PhenoSense is the gold standard used in nearly all drug development efforts
