I had a low risk exposer means finger prick lancet prick during my blood test in government hospital .I assume and dot that technician are reused materials means lancet and pipette. I don't know status of previous person but remember that after 10 to 15 min of previous person lab man tested me. Due to that fear I tested myself in serum clinic with duo HIV 1 and 2 and p24. Result is 0.17 negative. But now I noticed and read at net in many place that medicine may be affect window period or test. BECAUSE I had jaundice and now my jaundice level is decrease but now I treated with homeopathy doctor he prescribed me NV 200 and cold Q which are homeopathy medicine which I am taking .so my questions are. 1) can 3.5 month my HIV 4 gen test is conclusive? 2) can NV 200 and cold q medicine affect my negative HIV test result or window period? 3)can any thing or any activity or medicine affect 4 gn combo duo test results?
