Viracor’s HIV-1 Genotypic Drug Resistance Sequencing assay provides the fastest characterization—including subtype identification—of the most relevant viral genomic mutations known to confer resistance to antiretroviral drugs.

Significant Advantages of Viracor Genotyping

  • Detects the genomic mutations known to confer resistance to antiretroviral drugs
  • Estimates susceptibility to a growing list of approved medications referenced by the preeminent, curated Stanford University HIV Drug Resistance Database (HIVDB)
  • Excludes distracting test results (often included in alternative tests) that are unrelated to HIV drug resistance
  • Delivers industry-leading turnaround time: <6 days from specimen receipt
  • Reduces delays in getting patients on appropriate medications
  • Is available via HL7 interface for efficient, streamlined reporting and convenient access to actionable information
  • Identifies HIV-1 subtypes B, A, AE, AG, C, D and G
  • Is cost-effective

When to Order Viracor's HIV-1 Genotypic Drug Resistance Sequencing

Because HIV drug resistance changes over time, it is recommended that Viracor’s HIV testing be ordered at various stages in a patient’s journey. Consistent with NIH Guidelines, Viracor’s HIV testing is informative in:

  • Getting a baseline profile identifying current viral load
  • Problem-solving lack of response to therapy
  • Understanding patient deterioration
  • Getting clarification when considering a change in drug therapies

Know Your Patient's Susceptibility to Approved Antiretroviral Drugs

Viracor’s Genotyping estimates a patient’s susceptibility to:

  • NRTIs
  • NNRTIs
  • PIs
  • INIs

Why Advanced Subtyping Makes Viracor Testing Most Beneficial

As new HIV strains continue to emerge* in a virus with high genetic variability, Viracor fulfills an unmet need for HIV-1 subtyping.

  • The Viracor Genotyping test reports HIV-1 and provides susceptibility estimates for these subtypes:
        - B, A, AE, AG, C, D and G
  • Alternative tests may estimate only HIV-1 B or may not identify the subtype at all
  • B subtype is most common, but 90% of cases worldwide are non-B
  • Non-B is on the rise in the US
  • As non-B prevalence rises, Viracor’s assay will deliver a growing body of knowledge about treatment


The Stanford University HIV Database Assures that our Testing is Current on Approved HIV Antiretroviral Drugs

A patient’s susceptibility profile is determined by the Viracor HIV-1 Genotypic Drug Resistant Sequencing test, based on the curated Stanford University HIV Drug Resistance Database. For a complete list of regions evaluated, associated susceptibility, and references, visit:

Advantages include:

  • The Stanford database lists possible mutations and also includes links to supporting literature
  • Stanford updates the database continually. Viracor incorporates the newest updates in its reporting. Physicians receive reports based on current, curated data to support drug therapy decisions
  • The database stores, analyzes, and makes publicly available HIV drug resistance data from HIV researchers and clinicians
  • Stanford helps identify gaps in drug resistance information and updates its information through retrospective or prospective studies
  • Other HIV drug resistance testing may use only a lab-developed algorithm
