How long does it take to get results back from an HIV test? Results from antibody tests that are sent to a laboratory usually take one to three days to return. If the test is positive, results may be delayed while the laboratory does a Western blot to be sure that HIV antibody is present.

Results from rapid tests done in the doctor's office or at other points of care are usually available in 15-20 minutes.
