Varies: Results from antibody tests 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. Western blot tests take only one day to perform, but some laboratories may not run the test every day. Results from rapid tests done in the doctor's office can be 15-20 minutes.
