WebMar 27, 2024 · PCR can detect all types of bacteria, parasites, viruses and fungi, starting with DNA or RNA. While the principle and ingredients are similar, each use requires specific primers or probes to detect different organisms. That's why something for SARS-CoV-2 had to be developed from scratch. WebJan 18, 2024 · What do results mean for a COVID-19 PCR test? A positive result happens when the SARS-CoV-2 primers match the DNA in the sample and the sequence is amplified, creating millions of copies. This means the sample is from an infected individual. The primers only amplify genetic material from the virus, so it is unlikely a sample will be … fms truck parts
