Yes in part: The tests that detect actual HIV virus, such a the HIV viral load (pcr), will likely be positive 5 weeks after an exposure that results in transmission of hiv. The HIV antibody test may still be undetectable. So, if you are very worried about acute hiv, it is very important to discuss with your health provider so they do the right tests.
