A member asked:
If i do a 4th generation hiv test in a laboratory, will the result be reliable in 40 days or should i wait until 45 days?
A doctor has provided 1 answer
Six weeks is the recommended period. If the result is negative at 40 days you are unlikely to have HIV infection. For your peace of mind, you may repeat the test in 2-3 weeks. For info on HIV test window periods https://www.cdc.gov/hiv/basics/hiv-testing/test-types.html
