This test uses nucleic acid amplification techniques such as RT-PCR or other molecular methods.

It identifies viral genetic material (RNA), confirming the presence of SARS-CoV-2.

Clinical uses include:

Diagnosing active COVID-19 infection.

Screening symptomatic and asymptomatic individuals.

Supporting infection control and public health measures.

Confirming infection in patients with suspected exposure.

The test is performed on nasopharyngeal swabs, throat swabs, or other respiratory specimens.

Results are qualitative: reported as Positive (virus detected) or Negative (virus not detected).

Analyte: SARS-CoV-2 viral RNA.

Normal Result: Negative (no viral RNA detected).

Abnormal Findings:

Positive result: Confirms active COVID-19 infection.

Negative result: No viral RNA detected (does not rule out infection if sample quality is poor or taken too early).

Clinical Use:

Provides a definitive diagnostic tool for COVID-19.

Helps guide isolation, treatment, and contact tracing.

Used in screening programs for healthcare workers, travelers, and high-risk populations.
