Suppression Management GenoSure Archive® R6000 551776 In patients with suppressed or low level virus (less than 500 copies/mL), detects resistance in HIV-1 to antiretroviral drugs (NRTIs, NNRTIs, PIs, and INIs).
Suppression Management Super Panel GenoSure Archive® and Trofile® DNA R6000S/E3600S 552020 In patients with suppressed or low level virus (less than 500 copies/mL), detects resistance in HIV-1 to antiretroviral drugs (NRTIs, NNRTIs, PIs, and INIs) and provides co-receptor tropism status.
Co-receptor Tropism Testing Trofile® E3100 553100 Detect HIV-1 coreceptor tropism to determine patient eligibility for a CCR5 antagonist.
Co-receptor Tropism Testing Trofile® DNA E3600 829670 Detect HIV-1 coreceptor tropism to determine patient eligibility for a CCR5 antagonist.
Co-receptor Tropism Testing Trofile® Select

MGB E3000

LCA 553355

Determines HIV-1 coreceptor tropism status by selection of the appropriate assay, Trofile or Trofile DNA, through an initial prescreening viral assessment.

Viral Load Reflexing

We can perform a viral load test and then automatically run a resistance and/or tropism test if the patient’s viral load meets or exceeds the viral load thresholds for the chosen assay. The Labcorp test numbers for this automatic reflexing are below:
