Understanding your results You may have tested reactive on a rapid test. The test is likely to be very accurate if you ordered it or purchased the test from a reputable source. The reactive result means that HIV antibodies have probably been detected in your blood. For certainty, you should have a confirmatory test at a clinic where your blood will be taken. This result can take up to a week to receive the result. It is not unusual to feel scared and lonely during this time. Talking to someone during this time can be extremely helpful and comforting.
