Human Immunodeficiency Virus 1 (HIV-1) Trofile® Select
Also known as: Coreceptor Tropism (Phenotypic), HIV Coreceptor Tropism Phenotype, Tropism
Use
Trofile® Select allows for the determination of HIV-1 coreceptor tropism status, by which the appropriate assay, Trofile® or Trofile® DNA, is selected through an initial prescreening viral assessment. The coreceptor tropism status may be used to determine eligibility for CCR5 antagonist therapy, such as maraviroc (Selzentry®).
Special Instructions
Both frozen plasma and frozen whole blood are required for this profile. If both samples are not received, the order for the assay will be cancelled.
Limitations
This procedure should be used only for patients with documented HIV-1 infection.
