PCR Assay

A PCR (Polymerase Chain Reaction) assay is a laboratory technique used to detect and amplify tiny amounts of DNA from a sample. It works by repeatedly copying specific DNA segments through cycles of heating and cooling, which allow enzymes to replicate the DNA quickly and precisely. This process makes it easier to analyze or identify the genetic material, such as detecting a virus, bacteria, or genetic mutations. PCR is widely used in medical diagnostics, research, and forensics because of its accuracy, speed, and ability to work with very small samples.
