A PCR test involves several steps: 1. Sample Collection: A biological sample is collected, often via a swab from the nasal or throat regions, blood, or other body fluids. 2. Extraction: The nucleic acids (DNA or RNA) are extracted from the sample. 3. Amplification: Specific segments of the pathogen's genetic material are amplified using a thermal cycler and specific primers. 4. Detection: The amplified genetic material is detected and analyzed, confirming the presence or absence of the pathogen.
