Could you help? I have a few questions about HIV

[blackandblue42]

Hello i am very confused about many things i have read on the web about HIV and was hoping to get some accurate answers.  1. Is it possible that the single drop of blood that a rapid HIV test uses couldn't have enough antibodies to show up positive?   2. Is it possible to have a faulty test that produces a "false negative" after window period "3 to 6 months"?  3. nothing in medicine is 100% so how long or how many tests are needed to be 100% sure you are negative? 4.Does it matter what generation the rapid tests are...or are they all very reliable? Thank you.

  In an adult, a positive HIV antibody test result means that the person is infected, a person with a negative or inconclusive result may be in the “window for 4 to 6 weeks but occasionally up to 3 months after HIV exposure. Persons at high risk who initially test negative should be retested 3 months after exposure to confirm results

Post the link where someone had a rapid test at 3 months and then tested positive. Because your not going to find anyone who has tested positive after they have a 3 month test.

Also the Dr's have stated that they have not seen anyone on this site test positive.

iv read in the Dr forum that people have had rapid tests and they were negative. .. but then went in and had a test that looks at the virus itself and found they were indeed positive...not sure of that name..is that test necessary to be 100%?

doesnt matter the generation...3 months is conclusive and further testing is not needed.
