Hi all... I want to thank everyone that has helped me in my previous posts. I still have a question however about the window period for the DUO test. I had an exposure almost 8 weeks ago and have since had (non-reactive) negative DUO tests at 19, 33, and 41 days post exposure. I actually went to an HIV specialist at Northwestern Memorial Hospital (A nationally ranked hospital in Chicago) at the 41 day point and the Dr. told me that I was conclusively negative and required no more testing.
My anxiety is still high however because this information does not match what the CDC says. I know that some of you have said in previous posts that the CDC changed their recommendations in 2014 and that is why the non-expert forum now recommends that testing is considered conclusive at 28+ days instead of the typical 12 weeks.
The only updated recommendations I have found about the CDC says that most people will develop antibodies by 6-8 weeks and that P24 antigen will be detected 4-7 days before antibodies are produced. So does this mean that it is possible for the P24 antigen to not be present/detectable until 7 weeks? Also, on the CDC's website they give a very generic statement that testing for the P24 antigen reduces the window period, but does not (as far as I have been able to find) give an actual window period for the 4th gen test.
Does anyone have a link to the new CDC guidelines that actually give a window period for the DUO test? Nursegirl6572 I would really like to hear from you since I know that you recently started telling people that 28 days was conclusive since in your older posts you still recommended 12 weeks. What made you change your advice.
I greatly appreciate you all!
