Was tested with HIV 4th generation test at 52 days and 146 days after suspected exposure. Both Negative. 

Medications that have been used is steroid eye drops (prednisone) and omega 3 fish oils. Would these have any impact on the testing to make it false negative? Just had a lot of anxiety. Are the tests conclusive? 

Thank you so much! 

Your test results are conclusive.  4th generation, combination HIV antigen/antibody tests are entirely conclusive any time more than 42-45 days following an exposure of concern.  Thus, both your 52 and your 146 day tests rule out the possibility that you acquired HIV.  Falsely negative tests are extraordinarily rare and with two negative tests there is no chance than in infection would have been missed.  Neither prednisone eye drops nor omega 3 fish oils would interfere with the reliability of your test results in any way.

There is nothing to worry about and certainly no need for additional testing.  You are in the clear.  EWH
