A rapid HIV test from 10 weeks and 5 days from the encounter should be accurate. It may be advisable to go to the Health department or your primary care doctor to get a blood test as well. You may be interested in pre exposure prophylaxis; there are two oral drugs as well as injectables that are very effective to prevent HIV.

Thanks for the question. The test is accurate from 45 to 90 days after acquisition of the virus.
