4th generation DUO test results conclusive ?

Question: 

Hello,

I had an exposure due to broken condom with a CSW about 4 months ago.
This is my only exposure.

After that I got tested few times with 4th generation DU test as below.

1. 6 Weeks after exposure - NonReactive.
2. 10.5 weeks after exposure - NonReactive
3. 13 Weeks after exposure - NonReactive.

in between , I used a dose of antibiotic for throat infection & also eye drops with steroids.

Would this affect the test results ?
Should I consider these results as conclusive or test after 6 months.
Please advice.

thanks for your help in advance.

Answer: 

Hello,

Thank you for your inquiry. From what we gather from the question, you were asking about the risk of acquiring HIV after engaging in sex with a broken condom and the conclusiveness of three 4th Generation HIV DUO Ab/Ag tests. From the information given, this scenario is determined to be High Risk (evidence of transmission through these activities and is the majority of cases of transmission). Protected sex is typically identified as low risk, but since you noted that the condom was broken there would have been a period of time in which you were engaging in unprotected sex, which is a high risk activity.

The scenario mentioned above does meet the three components of the Transmission Equation. It is very responsible of you to access testing after engaging in risky activities such as sex with a broken condom. Most HIV specialists agree that 4th Generation HIV DUO Ab/Ag test are considered conclusive 6 weeks post-exposure (1). Some physicians and guidelines recommend re-testing after 12 weeks for completely conclusive results. Since you accessed testing outside of the window period you can be assured that the negative result is accurate. Also, it is important to note that other infections and medications do not affect the results of an HIV test (2).

Recommendation: No need to refer to a physician for an HIV test since you have already accessed testing outside of the window period. Refer to a physician for other health related questions.
