Window period ref

[down742]

These are the % of testing HIV anitbodies
1 week test：22.6%
2 week test：53.775%
3 week test：84.1%;
4 week test：98.4%
5 week test：99.45%
6 week test：99.994%
7 week test：99.99986%
8 week test：99.999999979%

This information is base on ELISA 3rd genaration

So I think why Dr HHH and Dr Hook is confident on 6 to 8 weeks test

3 months is when you can get your conclusive test result.

Are these figures for the window period pretty accurate for new rapid tests that take blood from ur finger i.e not full blood draw? I had a negative 6 week + 1 day result using that new Biolytical INSTI HIV test that gives results in 60 seconds (did it in the UK).

FDA instructs to reject donations from MSM and IVDU, because the odds of transmission are too high even with the testing.
This donation probably should have been rejected in the first place.

[regularjoey]

The problem is that there is a serious shortage of organs, so doctors have no choice but to accept pretty much everyone, even MSM and IVDU, and hope that the tests work.  But I have no idea why the NAT was not done.  The only reasonable excuse would be that the organs cannot be stored for more than an hour or two, which would make a PCR impossible.  We'll see, CDC is investigating this.  There'll probably be some lawsuits as well.

[Teak]

Knock it off. You are negative. PERIOD..

[chintoo982]

Can somebody tell me if my 2nd negative test ( elisa method) result done after 173 days in INDIA post a oral exposure(fellatio peformed on me) is conclusive or not? am really scared...been trying to follow up back to back...please help....and can any body acquire it from a cut by a razor at a salon..don't remember seeing any blood on it..reply will be appreciated

What is strange is that they knew he had engaged in high risk activities. I suppose they decided that they had to move.
But can PCR testing actually take so long that the organs can go bad?

Also, what are the odds of finding a donor that was in their window period? How strange. The only other possibility is that the donor had died in late AIDS and his core antibody had disappeared. Would that have been possible? Surely someone with a compromised immune system would not be able to become an organ donor? Or am I wrong here?

Finally, isn't there a flaw to with NAT, in that they only become accurate after 9-11 days, and even then you have false positives and negatives?

The poor people who were infected.

[regularjoey]

I guess they couldn't wait - organs probably go bad quickly (but I don't know for sure).
I hope they weren't just trying to save some money...

[regularjoey]

By the way, HIV testing is all over the news today.
An organ donor in Chicago infected 4 organ recipients.
Unbelievable...

[regularjoey]

I'm not here to fight and I won't fight with anyone.
I will however do my best to prevent people from misinforming others.

[inadepression]

fight fight fight!!! LOL

Come onnnn.. You two are great people.
You are doing great job here.
You are the most expert people in this forum.
Thanka teak, regularjoey..God bless you

[regularjoey]

Teak, FYI a 4th generation ELISA does have a p24 test in it.
I suggest that you don't correct people on subjects that you are not familiar with yourself.

[Teak]

Yes your test is conclusive.

[abathen]

I have tested at 28 weeks post sexual exposure with CSW. Is the result conclusive?

[Teak]

How many time have you read the timeline for obtaining a conclusive negative test? It's been explained many of times those that may need to test longer than 3 months. There has never been anyone on this forum that has needed to test out to 6 months.

[cybercondriac]

"...the 3% is for those people who don't use condoms consistently and condom failures."

Teak it seems like you may have thrown a wrench into the statistics theory debacle now. Are you saying the 3% are the ones that had condom discrepancies between 3 and 6 months, or before 3 months-just trying to decipher your answer.

[Teak]

No the 4 generation ELISA doesn't have a P24 test in it.

abathen, the 3% is for those people who don't use condoms consistently and condom failures.

[abathen]

Your reply really is comforting to read, even though it cant be verified and its not the official guide. The REAL problem is CDC's numbers; 97% for 3 months and 99.98% for 6 months. These figures are WAY off from your chinese doctor's figures!!!. 3 % means in every 100, 3 people will still need to test at 6 months!!! and what's that 0.02% even testing at 6 months?
Does anybody know how they actually derive such figures?
I would like to see the link to the chinese doctor's statements, maybe I could get a friend to translate it.

[down742]

also I read a post saying Elisa 3rd generation is more sensitive then the 4th one, because 4th added the p24 thing. but don't know is that truth or not. I really hope some HIV expert or some people who work in a lab can give some comment.

That's true... haha

[down742]

I think the doc must be Dr. HHH right?
Reading his reply always makes you feel better
Dr. Hook usually don't reply if you have further questions. haha
What's your symptoms? I have the same case with you test a bit early 5 1/2 weeks. I wore condom and I am still very worry and it just drive me crazy. So I understand how bad people feel when they are waiting for the window period.
If I am CDC, I will tell people 1 year is conclusive, because I will never be wrong.
I read a post in this forum saying some Australia hopistal saying 6 weeks conclusive and Dr HHH reply and saying that guy should trust them because Australia is the best country in the world to due with HIV
So I believe the world is making a change, but if I am goverment don't move is the best move.
I fully understand CDC's point of view.
Put it in the other way, why Elisa have 4th generation if the anitboies can only be detect close to 3 months anyway? Elisa can always stay in the 1st generation right?  Hope my english is not difficult for people to understand

[down742]

From my understand there is always no 100% in this world. I have even read a news about a guy confirmed HIV positve and turns into negative. But 99.9999999999999999999% people won't have anitbodies like him. So there is always a chance. 3 months turns positive in normal people, maybe just 1 in few millions, so I won't take it that serious, even Teak will say 3 months negative, you are safe. If you are that 1 in few millions, I will say you are just bad luck.
Consider there is always chance a plane fall on your house, but I don't think you will beware of that when you are sleeping
