PCR can be used to identify SARS-CoV-2 by detecting its genetic material.

• A. False
• B. It depends on the assay
• C. True
• D. It detects antibodies

Answer: (C)

Detecting viral genetic material with PCR is how SARS-CoV-2 testing is carried out. Because the virus is an RNA virus, the standard approach is reverse-transcription PCR (RT-PCR): viral RNA from the sample is first converted to DNA, then specific regions of the SARS-CoV-2 genome are amplified. If those viral sequences are present, the amplification produces a detectable fluorescent signal, confirming a current infection. This approach targets viral genes (such as N, E, or RdRp) to ensure specificity. It’s different from antibody tests, which detect the immune response rather than the virus itself. Even though individual assays may vary in targets or performance, the fundamental principle remains that PCR detects the virus’s genetic material, so the statement is true.
