Bodily fluids transferred? No test could tell immediately.Most tests are for antibodies, the soonest would show positive in +3 weeks after the encounter.If negative, wait for 3 months and test again & in 3months more.In the meantime, keep using all the prevention protective measures for HIV and, if you think you’re at High risk(I.e. partner was HIV positive) talk to your PCP about starting meds.
