Hello and thank you for your inquiry.
We understand that you are asking about the accuracy of multiple HIV test results you received, after engaging in protected sex.
Protected vaginal sex is considered to be a Low Risk activity for transmission of the HIV virus. This classification means that evidence of transmission occurs through this activity when certain conditions are met. In the case of protected vaginal sex, an example of such a condition would be condom failure or misuse. The presence of vaginal blood on your hands would not increase your risk level beyond low risk.
EIA (Enzyme Immunoassay) antibody 3rd generation aka ELISA:
This test has a window period of 4 weeks to 3 months (although up to 95% of infections are detectable within 4-6 weeks). Most people develop detectable antibodies in 21-25 days. (1) By your account, you had this test performed four times, all beyond the 3 month window period. You can consider each of theses four test results to be conclusive.
Fourth Generation EIA test (antigen-antibody combination test or DUO test):
Fourth-generation HIV tests can detect HIV infection in 50% of people by 18 days after infection; 95% of people by 34 days after infection; and 99% of people by one and a half months after infection (1). Fourth-generation HIV tests have a sensitivity of about 99.9%. (1) You had this test at 100 days, which is beyond the window period and you can therefore consider your result to be conclusive.
Recommendation: HIV testing is recommended for low risk activities. Since you have been tested multiple times, no further action is required.
