How is pcr used to detect viral infections
Web(PCR) is the most commonly used nucleic acid detection assay. It is estimated that PCR is 10 to 1000 times more sensitive than virus isolation. Detection of BVDV by PCR requires that genomic RNA be extracted from the sample of interest. This can be problematic as RNA is rapidly degraded if exposed to Rnases, which are ubiquitous in nature. Web4 aug. 2024 · Tests that detect current infections with SARS-CoV-2, the virus that causes COVID-19, are known as viral tests.There are two types: a Nucleic Acid Amplification Test, or NAAT, and an antigen test.
