SARS-CoV-2 Nucleic Acid Gene Target Detection (Qualitative) by Probe-Based Assay
This test detects genetic material from the virus that causes COVID-19 in your sample. It helps determine if you have an active infection.
["A positive result suggests recent COVID-19 infection; a negative result may mean you’re not infected or the test was taken too early."]

What This Test Measures
The test looks for specific genetic sequences (genes) from the SARS-CoV-2 virus in your sample. These sequences are unique to the virus and are used as a molecular fingerprint to confirm infection.
How the Test Works
Your sample (likely collected from nasal or throat swab) is analyzed using a probe-based method that detects viral RNA. This method amplifies and identifies the virus’s genetic material if present.
When to Expect Results
Results are typically available within 24–48 hours, depending on lab processing times. Follow-up instructions from your healthcare provider will guide next steps.
Why This Test Matters
This test is critical for diagnosing COVID-19, especially when symptoms are mild or unclear. It helps guide treatment decisions, isolate infected individuals, and monitor outbreaks.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Clinical significance: A positive result confirms an active SARS-CoV-2 infection and may require isolation, treatment adjustments, or further testing. A negative result does not rule out infection if symptoms persist or testing was done too early. Results should be interpreted alongside clinical findings and patient history.
