When it comes to testing for Covid-19, one of the commonly used tests is a PCR test. Polymerase chain reaction tests are a fast, highly accurate way of diagnosing certain infectious diseases as well as genetic changes. They work by finding the DNA or RNA of a pathogen or abnormal cells in a sample.
DNA refers to the genetic material that contains instructions and information for all living things. RNA is another type of genetic material that contains information that has been copied from DNA and is involved in making proteins. A lot of viruses and other pathogens contain DNA or RNA. Rapid antigen test, unlike many other tests, can find evidence of disease in the earliest stages of infection. Other tests may miss early signs of disease since there are no enough viruses, bacteria, or other pathogens in the sample, or the body does not yet have enough time to develop an antibody response. Antibodies are proteins made by the immune system to attack foreign substances, like viruses and bacteria. PCR testing can detect disease when there is only a very small amount of pathogens in the body. So what happens during a PCR test? During this test, a small amount of genetic material in a sample is copied various times. The copying process is known as amplification. In the event that there are pathogens in the sample, amplification will make them much easier to see. PCR is also commonly referred to as polymerase chain reaction, rtPCR, reverse transcription PCR, qPCR, quantitative PCR, real-time PCR. PCR tests are used to diagnose certain infectious diseases, identify a genetic change that can cause disease, and find small amounts of cancer cells that might be missed in other types of tests.
