Dr Wohl need your advice
Jun 7, 2013
hello Dr. Whole, I'm 23 year years old Asian guy I need to ask Can n 4 th generation duo test detect chronic hiv infection? I'm asking this because I had a high risk situation in 2007 and after that I never had any risk situation I had 5 hiv tests in 2011 and 2012 all tests were 4 th gen duo(genescreen ultra Ag/Ab Bio-Rad) in my situation I did this 4 th gen test after 4 and 5 years from hiv exposure so my infection is not a recent (acute or primary) I have heard this test use to detect recent(acute or primary) hiv infection. So this test not conclusive after 4 or 5 years from possible exposure? Please answer.Am negative? should I do 3 rd gen elisa test? or western blot?
Response from Dr. Wohl
The duo or combo test looks for antibodies and parts of the actual virus. That means it can detect HIV sooner than antibody tests alone. But, there is no reduction in the ability of the test to pick up longer standing HIV. Your testing proves you are not HIV infected and you need no other testing for HIV.
