Ok then is there an alternative to know if im infected with hiv2?

Thx

[Teak]

Antigens for HIV1.

[sillybilly911]

Hey teak just wondering.. If one was infected with hiv2, would he have the p24 antigen in his body on this only applies to hiv1

Thx

[Teak]

There are no antigen tests for HIV2 so 4 weeks would not be conclusive.

Thanks for the clarification nursegirl :o)

Basically, a DUO is recommended to be taken at the 4 week mark.  If the new recommendations state that a negative 4th gen DUO doesn't require follow up testing, it's pretty much saying that the 4 weeks is conclusive (for THAT test).

I'm sure as time goes on, the CDC and other agencies will spell out the new recommendations in a slightly more user friendly manner.  Hope so anyway.

[anonymous7567]

in chart its not written that 4 weeks is definative for fourth gen but it can detect 4 week earlier..so if guidelines before were 3 months ..so now with 4th gen its 2 months???I am confused

[Teak]

Don't hijack other people's threads.

[Veryworriedgirl9]

what are the new guidelines for nPep?

Thank you Teak, I know your knowledge is excellent, so hearing this from you does help a lot. Thank you for the good work you do. 2.4 days till 12 weeks then I can put this behind me.

[Teak]

Non of those are related to ARS or HIV.

[Luis10]

This is driving me crazy, mainly due to burning tingling in penile along with burning sore throat for 5 weeks now and stinging rectum with red blood today after wiping.

My HIV tests (can I move on) unprotected sex with female 9 weeks ago, not CSW or drug user. (all negative)

11 days - 4th gen
5.3 weeks - 4th gen
7.3 weeks - 3rd gen
8 weeks - 4th gen combo (20min) & 3rd gen rapid (1min)

[nursegirl6572]

No, it's saying that a rapid test would not be the test of choice in the algorithim as the first step in the new testing recommendations.

Rapid tests are still accurate, and when taken out to 3 months post exposure, are definitive.

[Luis10]

Is this saying that a rapid finger prick blood test with 20 minutes results are no longer seen as accurate ?

[nursegirl6572]

And, as for the exception, I'm pretty sure they're talking about the rapid test being excluded.  In order to be within their guidelines, one would have to use a standard lab drawn test I imagine.

This is all very new information, officially, and I'm glad to see it, so there's more consistency between what the expert docs are recommending, and the official guidelines.

I'm sure it will take some time before a lot of associated sites are updated.  I've seen links to the new guidelines, but the old verbiage is still there, which definitely can be confusing, especially for people who aren't at ALL familiar with HIV testing in any capacity.

[nursegirl6572]

Which sites, Teak?

[mikey29287]

Yeah I noticed that too regarding when one should test.

[Teak]

Number 1. on the chart.

1. Laboratories should conduct initial testing for HIV with an FDA-approved antigen/antibody combination immunoassay* that detects HIV-1 and HIV-2 antibodies and HIV-1 p24 antigen to screen for established infection with HIV-1 or HIV-2 and for acute HIV-1 infection

* Exception: As of April 2014, data are insufficient to recommend use of the FDA-approved single-use rapid HIV-1/HIV-2 antigen/antibody combination immunoassay as the initial assay in the algorithm.


None of the sites that say when one should test have been updated.

[mikey29287]

That seems to contradict the info given on the user friendly chart.

[nursegirl6572]

It looks like they excluded the rapid tests, and the HIV-2 NAT tests (due to them lacking FDA approval).  I'm pleased to see that they included ONLY approved tests in their algorithim.  That will cut down on confusion between entities (ie CDC and testing manufacturers)

[plokoon81]

Glad to see i am not a spammer  :) thank you guys

[mikey29287]

So it would seem a negative duo test at 4 or more weeks is considered reliable, and a follow up test at 12 weeks to exclude both types of virus, keeping in mind that hiv-2 is rare.

I wonder if the doctors from the expert forums attended a meeting to help formulate the CCDs new guidelines.
