THIS forum maintains the advice of 3 months based on the official testing guidelines set up by the testing manufacturers and the CDC. Until those entities change the window period, our advice will remain the same.
I will go back in 4 months time and see if it has changed - will post back here ...
FACT: There are no tests marketed or sold to give a CONCLUSIVE NEGATIVE test result earlier than 3 months post exposure.
The manufacturers of the DUO/COMBO say it is 99.89% accurate at 4 week--FACT.
The OFFICIAL guidelines from the manufactures is 3 months to obtain a conclusive negative test result.
You can go back in 3 Months and collect another negative if you like.
Just so you know I had my 5 week duo test .. negative .. doctor told me to put it all behind me and it will not change :\ .. now im not sure if I should put it behind me or go back in 3 months...
You are correct,the manufacturers of the DUO have stated that the test is 99.89% accurate at 4 weeks+ and DR Garcia and DR cummings both say this test is conclusive at 4 weeks+ regardless of the exposure and they say this time and time again.The US does not have the experience that the UK has with regards to the DUO nor do they have the same knowledge about this test.To silly_guy,if you have received a negative DUO at or after 4 weeks you are as good as home.Dr Sean Cummings is one of the best HIV experts in the UK and he is providing facts when he speaks of the DUO test.
Dr Sean Cummings from Freedom Health state that the manufacturers tell him that the tests are 99.89% at 4 weeks ... and he states it conclusive and definitive after 28 days... but I guess an antibody test at 3 months is 99.99% but I am very happy with a 0.1% difference..
especially when my risk (and others) was supposedly 0.1% (even less) with a female to male transmission...
I guess I will take a 6 week test and then a 4 month test and we could know !
The manufactures say that 3 months is when you can obtain a conclusive negative test result.
I guess so .. I guess for the DUO in Australia its conclusive after 6 weeks .... 42 days ? right ........which makes me think why should it be less in other countries ? Dr. HHH said supposedly the CDC is saying aswell that 3 months is way too long.
28 days will not give you a conclusive negative test result.
Hey guys .. just had my 33rd day test (bit paranoid thinking maybe 28 day was too early or could be a false negative..) and it came back negative !!(thank god) ... yet a little difference I noticed on this test that was different from the last one I had at a different pathologist and medical center ... is that this test says the window period is 6 weeks and the last one says 3 months .. yet they seem to be the same type of test ..
The last place was a general local medical center ... and this time it was an actual STD clinic.. I mean this STD clinic and pathologist must be fairly confident with 6 weeks ... if I go and test negative at 7 weeks ... and then afterwards test positive for HIV at 4 months, I could literally sue them for millions .. they are dealing with peoples health and lives here .. and I am sure they are smart enough to know this and have probably even allowed an extra 2 weeks ontop of 4 weeks to be safe ?? I feel the HIV experts on here and that I have seen are correct with saying 4 - 5 weeks is long enough.
I am getting another test results tomorrow for my 36th day test (over 5 weeks) and I doubt I will get a post 6 week test if this is negative, as the doctor said I could put all this behind me after my post 5 week test since I am not a IV drug user or ever had serious health problems etc.
I work with pathologists that use the DUO test everyday and the fact is that anyone infected with HIV will have high detectable levels of p24 antigen very early on,it will peak at around 3 to 4 weeks and then stay constant throughout the illness.This is the reason why it has an accuracy of 99.89% at 4 weeks.
they dont decline afterwards .. they stay high for a couple of of weeks (http://www.freedomhealth.co.uk/sexual-health/hiv-test-hiv-testing-london/125/)
so really unless there is a false positive .. supposedly 28 day test should be fairly reliable
Duo test looks for antigens that appear earlier than antibodies and peak at around 21 days,however it starts to decline after that..so you may take the standard ab test if u test after a 2 month period, which is good enough, but to follow the 3 month will give u total replief
The DUO is 99.89% accurate at 4 weeks,if you don't like those odds well I'm afraid it's not going to get any better than that.
Sorry I mean the antibody test is 99.99%
the difference "supposedly" between a 4 week hiv duo test and a 3 month test is 0.1% ... as the HIV duo test at 4 weeks is 99.89% and the 3 month antibody test is 99%
Obviously .. nothing in science or medicine is 100 percent right ?... even the 3 month tests are not 100 percent literally ... ? I just find it odd that 2 separate HIV specialists I have seen have said 4 - 5 weeks is long enough and I could claim it conclusive (duo test) yet the GP states that I have to wait 3 months... 99.89% is virtually conclusive to me if it is that after 28 days.
There are NO TESTS marketed or sold to give a conclusive negative test result earlier than 3 months post exposure.
