How do PCR tests detect COVID-19?

2 min read

PCR (Polymerase Chain Reaction) tests are instrumental in detecting COVID-19 by identifying genetic material from the SARS-CoV-2 virus. Here’s how the process works:

1. Sample Collection: A healthcare professional collects respiratory secretions using a swab from the nose or throat of the individual suspected of having COVID-19.

2. RNA Extraction: The genetic material of the virus, RNA (Ribonucleic Acid), is extracted from the collected sample. This step is crucial as it isolates the viral RNA from other cellular components.

3. Reverse Transcription: The RNA undergoes reverse transcription to convert it into DNA (Deoxyribonucleic Acid). This step is necessary because PCR primarily detects DNA, not RNA.

4. PCR Amplification: The PCR machine amplifies specific regions of the viral DNA through multiple cycles of heating and cooling. Each cycle doubles the amount of DNA, making it detectable.

5. Detection: Fluorescent markers or probes specifically designed to bind to SARS-CoV-2 DNA sequences are used. If the virus is present in the sample, these probes will emit light, indicating a positive result.

6. Analysis: The PCR machine detects and records the amount of fluorescence emitted after each cycle. A higher amount of fluorescence indicates a higher viral load in the sample, which helps determine the severity of the infection.
