SARS-CoV-2 Nucleic Acid Detection (Real-Time Polymerase Chain Reaction)

How the Test Works

The test uses a process called real-time polymerase chain reaction (RT-PCR) to identify the virus’s genetic material. A swab sample is collected from your nose or throat, and the lab analyzes it for the presence of the virus’s unique genetic code.

Sample Collection

A healthcare provider will collect a nasal or throat swab sample. This is usually done during your visit to the clinic or testing center. The sample is then sent to a lab for testing.

When to Get Tested

You may need this test if you have symptoms of COVID-19 (such as fever, cough, or shortness of breath), have been exposed to someone with COVID-19, or are required for travel, work, or school purposes. Always follow guidance from healthcare providers or public health officials.

Test Results Interpretation

Results are typically reported as either **positive** (indicating an active infection) or **negative** (indicating no detectable virus at the time of testing). A positive result means you may be contagious and should isolate yourself from others. A negative result does not rule out infection entirely, especially if you have symptoms or were exposed recently.
