WHAT IS LEUKOCYTE DNA TEST?
DNA studies of all biologic specimens use a technique called “polymerase chain reaction” (PCR) to amplify the quantity of DNA being studied. The polymerase chain reaction technique has diverse applications in detecting mutations and rare sequences of DNA. The discovery of heat-stable polymerase led to the invention of the PCR machine. PCR has found its way into virtually all fields of biology, including medicine, evolutionary biology, and genetics.
