Window period 6 weeks From Massachusetts Center

[qhss81]

Dear all,
I think Massachusetts Center is one of the most  famosue Centers in the world  or it is the best ,we all agree about that.
However, the center say the window period for HIV is 6 weeks and longer than that is for a person has a highly compromised immune system.
everybody can read that on:
http://www.aac.org/site/PageServer?pagename=basics_home#window
And also there is other site say that on
http://www.aegis.com/
However I agree with them becasue in simple Dr.HHH and Hook said there is no case turn positive after 6 or 7 weeks for all risks (HIgh,Low)
What are your say?
Thanks

Dear friend,
Is the last rapid HIv1/2 test in 10 years ago deffirint of these days?
Thanks.

Yes, it is true.
CDC uses 3rd gen and 4 gen.
So why so many HIV experts says 6 week conclusive.And these medical expert said Government always give more reliability and cover all kinds of people, its is 3 months.
Forget about 6 months, that is 10 years ago.

I'm assuming all of these 6 wk or 3 mo conclusive results are bsaed on newer geration antibody test too, right?  3rd gen EIA test, ICMA, etc.  I beleive the 4th gen look for P24 antigen too which could lower the window period too.  In the past (90's), it seemed like 3 mos was ok, but 6 mos was more conclusive.  I'm hoping the reason for lower window periods now is based on the 3rd and 4th gen testing available.

I called AIDS-HIV hot line, I asked the nurses about the question "Did you see anybody HIV test is negative 6 weeks, then changed to Positive  at 3 Month testing", She told me, she never saw that case.
And I asked Hiv expert ( USA famous HIV center chief scientiest) by internet chatting, if she had case 6weeks negative ,then changed to Positive, she said, she didn't see that, 6weeks is conclusive.
this is mI got information from recently study.

I agree with you ... and for other In very rare cases where a person has a highly compromised immune system, such as those in which a person has recently undergone chemotherapy or an organ transplant, it may take 3-6 months for their body to develop enough antibodies to test positive.
And Those who suggest window periods longer than 6 weeks are trying to account for all those who may also have compromised immune systems.

BUT I have question for you could you tell me where could you find CDC has never ever seen -ve test 6 weeks tourn to positive after 6 weeks because i have asked them before and they haven't answered me clearly just they put thier frequently answers.
Thanks.

6 weeks is the conclusive for heathy people. This is most HIV experts view. I checked data, CDC never see 6weeks negative , then change to Positive case in recently years.

Mass. still recommends a 3 month test.

[qhss81]

The test which is done after 6 weeks for most of people is conclusive and definitive as Massachusetts Center .
Maybe a lot of you ask what about the other if the test for most people I have just found the answer on this site http://www.aac.org/site/PageServer?pagename=basics_home
they said:

          Why do some sources advise waiting longer than 6 weeks for HIV testing?

Most people will test accurately for HIV after 6 weeks have passed since their last risk. In very rare cases where a person has a highly compromised immune system, such as those in which a person has recently undergone chemotherapy or an organ transplant, it may take 3-6 months for their body to develop enough antibodies to test positive. These are very extreme situations, however, and other more common conditions such as colds or the flu, diabetes, asthma, and many others, will not affect the body's development of HIV antibodies in that way. Those who suggest window periods longer than 6 weeks are trying to account for all those who may also have compromised immune systems.
Thanks.
