Window period ref

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

[stressed25]

where did you get those figures from?
thnks

[dying43040]

YEaqh hook says 4 week 85 90% and drh says at least 90%.Would be nicew though i have a 31 day negative

[down742]

I think we are using 4th genaration now, so it should take less time to detect the anitbodies for most healthy people. if you know cocktail method to treat aids, then you should know Dr. Ho.
Then you may heard a lady who work with Dr.Ho for 8 years. Her name is in Chinese, so I don't list out. She is 67 years old now and just retired this year. She is one of the leader in HIV field and she is the one who discover to test HIV anitbodies from urine. Magic Johnson's HIV was check by her.
Anyway, she claim that window period is 2 to 6 weeks.With the modern test. I believe in her, cause she has a lot experience and more than thousands patients. So 6 weeks, I know I am ALMOST safe.
Hope this information can make people worry less.
Also, she said the longer the syptoms (symptoms) the less chance it's caused by HIV

[abathen]

I was very interested in your posting. Does this lady work for the CDC? what does she says about 3 months and the 6 months window period? thanks?

[Teak]

The only way to know that you are conclusively negative is by testing at 3 months.

[ImStupid]

Where did you get this info from.  Do you have a weblink?  This would be very helpful for all forum users if you could post the link.

[down742]

I want to post the link but it's all in Chinese, if you guys can read chinese I don't mind to post.
Some more information, this woman is the most famous one in China about HIV, she has been working in US for many years and go back to China to control China's HIV spread. Also because of her, most China hosiptal consider 6 weeks and 8 weeks conclusive. Also one very interesting information, a HIV control hosiptal in China who has more than 770000 HIV cases say that none 8 weeks negative turns to positive in the past 17 years.  There are too many informations, I just can't list them all also my english is not that good.
Also to abathen, she said 6 weeks is already a bit long (most healthly people have anitbodies before 6 weeks and modern HIV test can test them out )and 3 months is like golden rule but she said people who said 6 months just don't want to take any responsibility.
I just want people who over worry can take a rest. take a test at 6 weeks or 8 weeks if your result is negative, then in most cases you will test negative in three months.
One more little thing which I don't know if it that truth. A doctor who study outside China said when he was having test in his exam, the answer for window period in the test paper is 5 weeks. (I think it's for normal people)
Anyway, Teak's three months theory is not wrong at all, it's like 0.001% still a chance but most people don't need to count it, that's what I thought.
if you guys still have questions, try to ask and I'll see if it the article have explained.

[inadepression]

is this lady a doctor or nurse_

[down742]

doctor

[inadepression]

Today, I talked to CDC again. I asked can healthy people produce antibodies after 3 months, he said yes! CDC really makes me crazy! I asked the teak's statement about the drug users, etc.. they rejected again. One side : U.S.A Governed Organization The other side: All western countries. It is unbelievable!

[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

[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]

That's true... haha

[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.

[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.

[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.

[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]

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.

[abathen]

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

[Teak]

Yes your test is conclusive.

[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.

[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]

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.

[regularjoey]

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

[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...

[stressed25]

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.

[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

[Teak]

Knock it off. You are negative. PERIOD..

[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.

[regularjoey]

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.

[helpplz03]

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).

[Teak]

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