Test three months after prep

Hi I had an exposure 28 february so I went and took prep for a month. After that I tested using biosure – neg result. Tested again 3months after my exposure using biosureĀ  – again negative result. So what I want to know is: when is my result conclusive?

Hi Sorry, Yes a negative result 3 months post PrEP treatment is conclusive and you do not need to retest. I hope this helps, Becky.

Hi so my result will be conclusive three months after prep?

Hi Sorry, Our test has a window period of 12 weeks - you can test at any time during this period but a negative result is not conclusive until 12 weeks post-exposure. PrEP and PEP are types of antiviral treatments that prevent HIV infection. However, these treatments can also delay antibody response and therefore you must wait another 12 weeks after finishing a course of either treatment to test for a conclusive result. So if your last possible exposure was 28 February and you took PrEP for a month following this, I would recommend that you retest 12 weeks after stopping PrEP. I hope this helps. Kindest regards, Becky
