[Question #792] Group p Hiv

52 months ago
Good morning,

Hiv test fourth generation is able to detect group p Hiv? 

I read that The test is not designed to detect it, but is able to detect group p; is it true?

Thanks

Welcome to our Forum.  I'll be pleased to comment.  I think you may have been mis-informed.  Group P HIV is a subgroup of HIV-2 which, like other HIV-2 subgroups is detected by currently available tests for HIV.  Further, Group P which was described from West Africa is the rarest of all currently recognized HIV subgroups.  If you were worried about HIV, were tested with an approved test, and found to be negative an appropriate time after your exposure, you can be confident you do not HIV HIV-2, group P, or any other type of HIV. 

I hope this clarifies things for you.  EWH

Thanks for clarify me The group . But at http://www.avert.org/professionals/hiv-science/types-strains says that hiv 1 has 4 groups (m,n,o,p) and Hiv 2. The american society says The existence of group n Hiv 1 as well

I did the fourth generaction test 2 Months after the possibly   risk and it is negative.  My doubt is, The Hiv test  is able to detect all groups or subtypes that actually Exist?

Thanks

You are correct and I misspoke, type P is a subgroup of HIV-1, not HIV-2.  Despite that, there is no information to suggest that an approved 4th generation test performed 2 months after exposure would fail to detect an HIV infection.  My advice is for you to believe your test results and move forward.  EWH

No, HIV is not spread by touching.  This is the case even if there is blood present or if you had a cut on your fingers- no risk.


As indicated in the Forum guidelines, this is my third and final response you your questions.  This thread will be closed in a few hours.   I will repeat, my advice once more- you should believe you test results.  You did not acquire HIV from the exposure of concern.   EWH
