Which blood test is used int the US?

My last risky sexual encounter would be 2-2 and a half months ago. I had an OraQuick rapid HIV test on May 26, which turned up negative. On May 29, I visited my gynecologist and had blood drawn. The blood was sent to the lab and I got my results today, which were also negative. Which blood test was mine likely to be? I live in the US. I hear that ELISA is 95% accurate by 28 days post exposure. Is it likely that my results will change?

If the lab did a 4th generation test then it is considered conclusive at 28 days or later.

A 3rd generation test is 3 months though experts feel a 2 month neg should not change.

What test you had?
Don't know, call your Dr and ask which one they ordered.

Sorry I don't know the answer. When they fill the script the Dr will indicate which one. It is mostlikely a 4th generation test being it greatly reduces the window period. 28 days or later for a 4th generation test or 3 months for a 3rd generation test. To surmise is not helpful. You need to contact your Dr or the lab that did the test to get your answer.

Standard antibody test was most likely done.

She said it was the antibody test. Would it be likely to change?

8 week antibody test is not going to change.

I am planning on taking a Home Access HIV test in the 12th week to double check. Do you have any experience with the test? Would you recommend it?
