LabCorp Unveils HIV-1 Next Generation Sequencing Assay - Quick Facts

Laboratory Corporation of America Holdings (LH) and Monogram Biosciences Inc., part of the LabCorp Specialty Testing Group, announced the launch of HIV GenoSure Archive, the first laboratory test to help optimize antiretroviral or ARV drug regimens in virally suppressed HIV patients. GenoSure Archive was developed using the Next Generation Sequencing or NGS platform.

Advances in HIV drug therapy have allowed patients to achieve and maintain complete suppression of viral replication. Life-long treatment, however, is necessary to maintain viral suppression. Such treatment therapies often have adverse side effects, and as new, more simplified ARV drug regimens become available, patients may benefit from new therapies.

Previous laboratory testing to guide ARV drug selection required higher viral loads than what many patients have, leaving clinicians without a reliable diagnostic tool to guide ongoing therapy choices. HIVGenoSure Archive is the first genotypic drug resistance assay specifically designed to reliably identify the HIV DNA compartment, and it provides physicians and other HIV care providers with critical diagnostic information to support individualized and updated therapies for patients with low or undetectable viral loads of HIV-1.

GenoSure Archive is performed by amplifying cell-associated HIV-1 DNA from infected cells in whole-blood samples and then analyzing the polymerase (pol) region using NGS methods. The assay is analytically validated to identify mutations associated with resistance to all members of the most widely utilized ARV drug classes.

GenoSure Archive evaluates the full-length protease and integrase coding regions and amino acids 1 to 400 of the HIV-1 reverse transcriptase region. Resistance interpretations leverage Monogram's database of over 150,000 matched phenotype and genotype test results.

GenoSure Archive was developed and is now available for patient testing and clinical trials exclusively through Monogram Biosciences.
