A screening test that detects the presence of antibodies in a person’s body by testing serum (blood or oral fluid). The body’s immune system produces these antibodies when infected with microorganism or foreign body
There are three types of results you could possibly receive from a Rapid test:
A Reactive or Preliminary Positive Result: This means antibodies were detected in your body. A confirmatory test will be given to eliminate the chance of a false positive result.
A Non-reactive or Negative Result:
A non-reactive or negative result means that the test did not detect any antibodies.
An Invalid Result:
This means that the foreign body cannot be interpreted. An invalid test result means there was a problem running the test, either related to the test device or the specimen. In this case, another test would be given.
