The coronavirus pandemic has impacted everyone; after all it has created a public health crisis that has led to an economic slump in its wake. Thus, it is crucial to control the spread of this deadly virus by all available means. One of the most efficient ways to achieve this, is by testing accordingly. The more knowledge healthcare professionals gain, the easier it will be to make decisions when dealing with the issue on how to handle this pandemic. Even though the development of a test required some time, there are now multiple options available. It is important that everyone understands how these coronavirus tests work.
Amongst those tests that people need to know about, is the antigen test. An antigen is a protein that is projected on the surface of a molecule. The COVID-19 antigen test has been designed to detect proteins that are associated with the virus. The test assumes that if these proteins are present in the bloodstream of the patient, it seems probable that they are infected with the virus as well. It needs to be noted that it is possible to have false positive or false negative results with any of these tests. Especially since there are some types of antigens that might trigger a positive test result even though the person has not been infected with the coronavirus. Overall, however, this is an accurate test for the virus.
The other common type of test that might be used to test for coronavirus s an antibody test. When someone has been infected with the virus, the body produces antibodies that instruct the white blood cells to attack the virus. The body requires a few days to produce antibodies. For that reason, the antibody test is not positive immediately. The purpose of the antibody test is to figure out if a person has an immune response to the virus. As a result, the antibody test will turn out positive if someone either has an infection or has had an infection at any point in the past. Nonetheless, it is possible that this test could have a negative test result if someone does not have any antibodies. This either happens if someone has never been exposed or if someone’s immunity has waned.
Finally, there is also the possibility of a PCR test being developed in the future. 8 strip PCR tubes with caps may be useful for detecting certain types of DNA. The aim of a PCR test is to determine if there is any foreign DNA present in the bloodstream. This could be the DNA of a virus or bacteria. The PCR test is going to amplify these strands of DNA and will turn positive if they are present.
This is a brief overview of the most common types of tests that are used to detect the coronavirus in people. These tests play a crucial role in addressing this current public health crisis.
