If my antigen test is negative, should I take another test?

If you are exhibiting symptoms, you should take another antigen test 24-48 hours later or get a PCR test. You should follow isolation guidance until you receive the results of the second antigen test or the PCR test.  

If you do not have a known exposure and are not exhibiting symptoms, there is no need to seek another test.
