instruction: hi doctor hiv tridot antibody test done at weeks and 10 weeks all negative are there chances it will turn positive at 12 weeks now test done with blood taken from vein
output: hi following is my opinion for your asked question hiv tri dot antibody test is having good sensitivity and specificity in ruling out hiv as like that of fourth generation elisa usually tri dot hiv test is able to rule out hiv after six weeks of exposure however hiv test can be considered conclusive in ruling out hiv after three month of exposure so I suggest you investigate with hiv rapid test after 12 week again you can revert back with hiv report after 12 week of exposure to check it
