What is the chance?

I took the Oraquick at 3, 4, and 6 weeks, then again at 65 days and all were negative. What are the chances of my results changing by the 12 week mark? I am so nervous!

Extremely unlikely a 12 week test result will be any different than your 65 day test result.

Consider this...the estimate is that 95 percent of newly infected folks will have enough antibodies present by one month (actually a tad less; 25 days) after transmission to show a "reactive" (i.e., positive) screening result. By 12 weeks this has increased to 99.99 percent.

Sixty five days falls somewhere inbetween but clearly closer to the 90 day mark.
