What This Test Measures

The test captures and sequences the virus’s genetic code (DNA/RNA) from a saliva sample. It identifies mutations, variants, or other genetic markers that may affect how the virus behaves or responds to treatments.

Why It’s Done

Healthcare providers may order this test to monitor emerging variants, assess infection spread, guide treatment decisions, or support research into vaccine effectiveness or antiviral therapies.

Sample Collection and Preparation

You’ll provide a saliva sample (e.g., using a collection tube) that’s sent to a lab for viral RNA extraction and sequencing. Results are generated from the genetic data extracted from the sample.

How Results Are Used

Results provide detailed genetic information about the virus, which can help identify variants, track transmission patterns, or inform personalized medical or public health strategies.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Clinical significance: This test supports real-time monitoring of viral variants, which is critical for adjusting public health guidelines, vaccine strategies, and targeted treatments to address evolving strains.

Frequently asked questions

Will this test show if I have COVID-19?
No, this test specifically looks at the virus’s genetic material to identify its strain, not whether you currently have an active infection. A positive result indicates the presence of a SARS-CoV-2 variant, but you may still need additional testing (like PCR) to confirm active infection.
How long will it take to get results?
Processing times vary by lab, but results are typically available within 1–3 business days after sample submission. Follow-up with your healthcare provider for interpretation.
Can this test replace standard COVID-19 testing?
No. While this test provides detailed genetic insights, standard PCR or antigen tests remain essential for confirming active infection, diagnosing severity, or guiding treatment decisions.
