PCR tests are highly recommended when it comes to diagnosing certain infectious disease and genetic changes. These tests are a fast and highly accurate. They work by finding the DNA or RNA of a pathogen (disease-causing organism) or abnormal cells in a sample.
DNA is the genetic material which contains instructions and information for all living things. RNA is another type of genetic material which contains information that has been copied from DNA and is involved in making proteins. Most viruses and other pathogens contain DNA or RNA. Unlike many other tests, a PCR test can help find evidence of disease in the earliest stages of infection. Other tests are likely to miss early signs of disease since there not enough viruses, bacteria, or other pathogens in the sample, or your body has not had enough time to develop an antibody response. Antibodies are the proteins that are made by your immune system in order to attack foreign substances, like bacteria and viruses. A rapid antigen test for travel can detect disease when there is only a very small amount of pathogens in your body. During PCR testing, a small amount of genetic material in a sample is copied multiple times, a process that is referred to as amplification. If there are pathogens in the sample, the amplification process will make them much easier to see. So, how are PCR tests used? These 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. They are very effective, hence why they are preferred when it comes to checking for the presence of the coronavirus disease.
