Rapid tests, also known as rapid diagnostic tests or RDTs, are easy-to-use tests that provide quick results, usually in 20 minutes or less. Most standard tests have to be sent to a lab, and you have to wait for the results. With a rapid test, you can have the test done and get the results at your provider's office or a clinic.
For some of these tests, you can also do them and get the results at home. Rapids tests usually include the following steps: You provide a sample of your body fluid, such as blood, urine, saliva, or nasal secretions.; The sample is mixed with a special substance that will cause a chemical reaction if a disease or other condition is present.; The results show on a dipstick or rapid test cassette: A dipstick is a thin, plastic strip coated with chemicals. If the test is positive, the dipstick will change color when placed in the sample.; A rapid test cassette is a small plastic case with a well that holds the sample.
The well shows a letter or a symbol to indicate the result.; ; Most rapid tests can provide quick, reliable results, but the results are not always as accurate as standard lab tests. The accuracy of your test results may be affected by: The type of test used; How the test is stored and transported; The type of specimen taken; Your symptoms; When your symptoms started; What you are testing for; Using a test that is past its expiration date;
