There are only two tests available to see if you are Covid positive. The first one is a PCR molecular test. This is a very sensitive test that is likely to be given to people who are being tested to find out if they are Covid positive. This test is inserted through the nasal cavity, and then placed into a buffer solution. A PCR test is also known as a Polymerase Chain Reaction test. This test will pick up the smallest amount of Covid particles within the nasal cavity, which is why it is known to be sensitive. This kind of test is only to test for Covid and will not pick up any other cold virus. The next kind of test is known as a Rapid-Antigen Test. A rapid-antigen test is known to be a denser kind of test. These tests are not recommended in identifying if you have Covid, as they only pick up large amounts of Covid particles. This test can be used either in the nasal cavity or oral cavity. If you have been recently infected with Covid and are having minor symptoms and use a Rapid test, you may test negative until you are further along in your Covid infection, as the virus takes time to replicate and leave its viral particles in different body cavities.
