Hello Doc,

Thank you for your response.

Well, the condom worked perfectly, I just went through the test since the HIV status of the other person was unknown to me.

I have uploaded the report, it doesn't say anything about the Generation. Is it a 4th Gen. Test? If not could you please tell me some 4th Gen. test name and are they valid in 6th week??

Hi Doc,

I called in to the lab and looks like they have no clue on the generation.
In the worst case, if we consider it as a 3 Gen, how conclusive you consider this result at 5th week???

Answered by Dr. Vivek Chail (6 minutes later)

Brief Answer:
HIV rapid third generation is to be done at 3 and 6 months

Detailed Answer:
Hi xxxxxxxxxxx,
Thanks for writing back with an update.

1. If they have third generation rapid HIV test then it is to be done at 3 months and again at 6 months. If negative after 6 months then it is conclusive. This is because the HIV antibodies can appear after 3 to 6 months.

Hope your query is answered.

Hello Doc,

I got my self tested again (CMIA method) at 34th day and it came as Nonreactive, attached the report.

What is you opinion, do I need any more test after 3 months?

Answered by Dr. Vivek Chail (1 hour later)

Brief Answer:
This test has to be done at 3 and 6 months to screen HIV infection

Detailed Answer:
Hi xxxxxxxxxxxxxxxxx,
Thanks for writing back with an update.

1. The test is for HIV antibodies for HIV 1 and 2 virus. This has to be repeated after 3 and 6 months. Since you have done protected sexual intercourse therefore the chances of HIV is less.
