COVID-19 PCR Testing

What is a PCR Test?

PCR (Polymerase Chain Reaction) is a technique used to amplify small segments of DNA or RNA. For COVID-19:

  • The test detects viral RNA (genetic material).

  • It is considered the "gold standard" for accuracy in COVID-19 diagnosis.

How It Works

  1. Sample Collection: A swab is inserted into the nose or throat to collect mucus.

  2. Laboratory Analysis: The sample is sent to a lab where:

    • Viral RNA is extracted.

    • It is then converted into DNA.

    • PCR amplifies the DNA to detectable levels.

  3. Results: Typically available within 1–3 days, though rapid PCR tests can yield results in a few hours.

When to Get a PCR Test

  • You have symptoms of COVID-19 (fever, cough, fatigue, etc.).

  • You've been exposed to someone who tested positive.

  • You're required to test for travel, work, school, or medical procedures.

  • You're part of a screening program or have been in a high-risk setting.

Advantages

  • High accuracy (especially compared to rapid antigen tests).

  • Detects virus even in early or asymptomatic stages.

Limitations

  • Requires lab processing (unless it's a rapid PCR).

  • May remain positive for weeks after recovery, detecting non-infectious viral fragments.
