I took a risk penetration without a condom in 10/09/2015.

What is the window period for an HIV test?

When I can do a test in order to be sure 100%?

What is the maximum term for the body develops antibodies? and they are the elements that delay the appearance of antibodies in some people?

Is the P24 antigen disappears after the appearance of antibodies? it is in the case of appearance of this antigen antibody remains behind in the blood (detectable level) and do not disappear after a few weeks later?

Thank you for your help.

Nota: During this period I had take Azix 500 for treating a disease

Hello and thank you for contacting the AIDS Vancouver Helpline. I understand you're worried about your recent experience, and I will be more than glad to answer your questions.

First, I'd like to mention that unprotected sex is a high risk activity for acquiring HIV, and it is good to hear that you're planning to be tested, since testing is the only way to know your HIV status.

The window period for an HIV test is 3 months after exposure. Therefore, you can go for a test now and your results are considered "conclusive". At that point, your results are 99.9% accurate. An HIV test, just like any other medical test is not 100% accurate since there is always room for human error.

Generally, most people that newly acquire HIV develop detectable antibodies around 21 to 25 days post-exposure, and would test positive after that time. However, the window period is stretched to 3 months to be safe. However, there are 4 conditions that can delay production of detectable antibodies even further than 3 months: treatment for cancer, treatment for Hepatitis C, PEP treatment for HIV, and other immunodeficiency disorders. If these conditions don't apply to you, then your test after 3 months is conclusive.

The P24 antigen does not disappear, however it peaks in the first few months of infection and it can be detectable.

Also, taking antibiotics such as Azix do not affect HIV testing or the window period.



All the best,

Ali
