The PCR (polymerase chain reaction) test is considered to be fast, a highly accurate in the diagnosis of the certain infectious diseases along with genetic changes. The different tests that work by finding and elaborating the DNA or the RNA of the pathogen (also called a disease-causing organism) or any abnormal cells that are present in the sample as given.
The parts of the genetic material that are assessed in PCR are the DNA and RNA. The details of which are given below.
Unlike any other tests, the PCR tests would be able find evidence of the disease in earliest stages of the infection. As other tests could fail in minute detection of the sample, PCR is an accurate procedure.
The Antibodies are the proteins that are made by the immune system which attack the foreign substances, for example: viruses and bacteria. The PCR tests make multiple copies of your sample and it would detect the disease.
During the PCR test, there are small amount of the genetic material in your sample which is copied in a multiple times. The copying process is also called as amplification. If there are any pathogens in your sample, the amplification would make them easier to see and assess.
