Measure resistance to current and future entry inhibitors. PhenoSense Entry™ provides unmatched clinical utility to help determine whether to start or discontinue Fuzeon (enfuvirtide). If a failing regimen includes enfuvirtide, a complete phenotypic picture of the virus is needed to determine which components to change, as enfuvirtide may still be effective.
