Hi,
I tested 6-7 weeks after exposure for hiv using fda approved 4th gen rapid test at clinical setting and it came out negative. I was waiting for 12 week mark but I am continuously depressed and couldnt bear it anymore so I have decided to go get teated again at 10 weeks..which is 2-3 days from now. My question is:
1-whats the difference in conclusiveness of 10 week and 12 week mark?
2-what kind of test should I take. Rapid test or the laboratory test..I have heard they both are same but differs only in time taken for getting results.
3- do I need to go again after 12 week to be sure or should I just blow it off based on the results of 10 week 4th gen ab-an combi rapid test.

Thanks in advance.

Hi there! Thank you for contacting the AIDS Vancouver Helpline with your HIV related questions and concerns. We are happy to help!

I understand you're concerned about your test results. Hopefully this information will be able to help you out.

I will answer your questions one by one:

1) In terms of the 4th generation Antibody test, most HIV Specialists actually consider it conclusive at 6 weeks. The BC CDC still says 12 weeks, but mostly because not all facilities carry the 4th gen test yet, so it's easier to say all tests are conclusive at 12 weeks for simplicity. That being said, at AIDS Vancouver we go by the BC CDC, which says 12 weeks, yet it is HIGHLY unlikely that your negative status would change. The exact conclusiveness of the 10 week versus 12 week mark is a complicated question, but basically the longer you wait the more accurate. Keep in mind though that your 6 week result, as I said, is technically considered conclusive and is highly indicative of your actual status.

2) The 4th generation test is the one that is considered conclusive the earliest. However, all tests are conclusive at 12 weeks so it's up to you.

3) This will be based on your personal level of ease. As I said, it is considered conclusive at 6 by HIV specialists, so if this puts your mind at ease, no further testing required. If you're still anxious about it, feel free to test at 12 weeks, but it's unlikely to change.

Check out the BC CDC Guidelines [HERE](http://www.bccdc.ca/NR/rdonlyres/B35EDEBD-98CA-48BB-AB7C-B18A357AC19D/0/BCHIVTestingGuidelinesMay2015.pdf)

Hopefully thishelped!

Sincerely,
Christina
