Antibody detection

Thank you for everything you do.

Is there significant variation in how many hiv antibodies someone has after seroconversion and if so what factors influence this?

I have done 2 Biosure tests (one 8 months post exposure and one 15 months) and both clearly negative.

What is the likelihood of me having hiv but the test not being able to detect the antibodies 15 months post exposure?

Hi Ryan81, Seroconversion usually occurs 1 - 4 weeks after initial infection at which antibodies are produced in response to the virus. Everyone produces antibodies at different rates. By 6 weeks, 95% of people will have produced enough antibodies for our test to accurately detect infection. And by 12 weeks, 99.9% of people will have developed detectable levels of antibodies. Both of your negative results performed well outside of the window period are very reliable and you do not need to retest. Kindest regards, Becky
