I was accidentally injected with a potentially contaminated needle at a clinic. Concerned about HIV risk, I went for an HIV combo test 56 days after the incident at my nearest ICTC centre. The test result was negative. The ICTC staff mentioned that if there is direct exposure to HIV infected blood, it can show in the test after 28 days. I would like a specialist advice regarding: Should I get tested again? Which test is recommended now? Is 56 days sufficient to conclude that I am HIV negative? I have heard that HIV transmitted via sexual contact may take longer to appear in blood tests compared to needle exposure, is this true?

HIV Combo test (4th gen) at 56 days is highly reliable. Low risk via needle prick unless blood was visible. For peace of mind, test again at 90 days.

I had sex with a prostitute 20 days ago, and the condom broke. Yesterday I developed a fever and visited a physician. After taking the prescribed medicine, my fever subsided within a day, but I still have a sore throat. Could this be related to HIV? Can I get an HIV 1 and 2 antibody screening test done and will it be reliable at this stage? Please advise, as I am extremely anxious.

Hi, my blood test report for HIV shows negative (0.06). What does this decimal number mean? I have taken this test after 72 hours. Should I take it again after a few days?

I had protected sex with a commercial sex worker in Malaysia for the first time in my life. Out of fear I underwent PCR DNA test and Tridot test after 35 days. Both results were negative. Please suggest further help? I am suffering from anxiety and depression because of guilt.
