HIV 1/ 2ag /ab combo test
i have a question . i got HIV ag/ ab combo screen test done ? what kind of test is that? does that look for anti bodies?
the results said : non reactive, HIV final interpretation: no HIV p24 antigen and no HIV 1/HIV 2 antibodies detected?
also another question
i got another HIV test done which was after 2 years of possible exposure and i am still worried i thought i will feel better after getting done after two years. this test was HIV1/2 AG / AB COMBO SCREEN. and it was non reactive and said no HIV p24 antigen and no HIV1/ HIV 2 antibodies detected. whats the difference between those two type of tests i mentioned ? and how accurate are they? do i need to retest again? two years is more than enough to know your status right?
and also i had a rapid test done as well and it was non reactive. what kind of test is a rapid test and how accurate is that?
please if you could answer me . i will wait for your reply. thank you.
and also even though you guys are not doctors or anything but the information you guys provide are accurate right?
i appreciate all your help . thank you . have a nice day
Hello and thank you for using the AIDS Vancouver helpline as source for your HIV related information. I will do my best to address your questions.
AN HIV ag and ab Combo or Duo test will look for HIV Antigens and HIV Antibodies. You can trust in these results as this 4th generation EIA test is one of the most accurate on the market (99.9%). This Combo test first looks for P24 antigens immediately after infection and only for the first 2 to 3 weeks. The second part of this test looks for antibodies and has a window period of between 4-12 weeks. Most HIV specialist will consider this test conclusive at 6 weeks.
HIV 1 is the most common form of HIV, while HIV 2 is a strain of the Virus usually found in Sub-Sahara Africa. You are correct after 2 years no further testing is required.
A Rapid or "point of Care" test also has a window period of between 4 weeks and 12 weeks with an accuracy rate of 99.6%. In Canada the Rapid test is administered by doing a finger prick and testing the blood immediately after. In the United states they use blood or oral swabs for their rapid tests.
