How do PCR tests detect COVID-19?

Polymerase Chain Reaction (PCR) Test for COVID-19 Detection

PCR (Polymerase Chain Reaction) tests are a cornerstone in detecting COVID-19 due to their accuracy and reliability. They identify the presence of the virus's genetic material (RNA) in a sample, typically collected via a nasal or throat swab. Here's how the process works:

1. 1. Sample Collection: A healthcare professional collects a sample from the patient's nose or throat using a swab.

2. RNA Extraction: The collected sample contains various substances, including the virus's RNA if present. The RNA is extracted from the sample using chemical reagents.

3. Reverse Transcription: Since PCR works with DNA and not RNA, the extracted RNA is converted into complementary DNA (cDNA) using an enzyme called reverse transcriptase.

4. Amplification: The cDNA is then subjected to a series of thermal cycles in a PCR machine. Each cycle doubles the amount of DNA, allowing even tiny amounts of viral genetic material to be amplified exponentially. Specific primers (short DNA sequences) and a DNA polymerase enzyme are used to target and replicate the viral DNA.

5. Detection: As the DNA is amplified, fluorescent markers attached to the DNA strands allow detection. The intensity of fluorescence indicates the presence and quantity of viral RNA in the original sample.
