Almost as good: The finger prick HIV blood tests are very good, almost as good as laboratory based blood tests. If enough time has passed since the last possible exposure, the result is conclusive. That's 4-6 weeks for the antigen-antibody ("combo", 4th generation) tests and 6-8 weeks for most antibody-only tests. The oral fluids test isn't quite as good, taking up to 3 mo. and still missing a few infections.
