This test uses Polymerase Chain Reaction (PCR) technology to amplify and detect viral RNA.

It provides a qualitative result: Positive (virus detected) or Negative (virus not detected).

Clinical uses include:

Diagnosing active COVID-19 infection in symptomatic or exposed individuals.

Screening patients before hospital admission, surgery, or travel.

Supporting infection control and public health surveillance.

Specimens typically include nasopharyngeal swabs, throat swabs, or other respiratory samples.

Considered the most reliable test for early detection of SARS-CoV-2.

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 (may require repeat testing if clinical suspicion remains high).

Clinical Use:

Provides a definitive diagnosis of COVID-19.

Helps guide isolation, treatment, and contact tracing.

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