Medical Conditions - Polymerase Chain Reaction

A polymerase chain reaction (PCR) is a laboratory technique used for making multiple copies of a segment of DNA (deoxyribonucleic acid). It helps in having rapid amplification of a specific segment of DNA. PCR is often used in diagnosing acute febrile conditions like falciparum malaria, salmonella, and babesiosis. It is most commonly used in genotyping, cloning, mutation testing, and paternity testing.
