Window Period 4th gen

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!

I understand that I do have an Anxiety problem and I am currently under a Psychologist's care for that. (& i'm trying my best to cope with the mental, emotional & physical symptoms of anxiety). My question is not so much asking for advice from a stranger (as you say) but asking if anyone on this forum has a link to an official governmental agency such  as the CDC regarding an officisl change in their testing recommendations/window period.

An HIV specialist from one of the top medical facilities In the country has stated that you are CONCLUSIVELY negative. And, your next move is to ask the advice of strangers on the Internet with unknown qualifications. This is not normal. As your doctor has instructed you, HIV is not your problem. Your true issue is your extreme anxiety and doubt in the face of overwhelming evidence. Your next move should be to contact a qualified mental health professional to help you cope with your debilitating anxiety.
