Now, my results have a little description here thats totally confusing: maybe the Dr or forum memebers might elaborate
#1The HIV Ag/Ab is 100% sensitive in detecting HIV infected patients that are not in the window period. Window period varies between 18 days to 6 weeks
#2 The negative HIV Ag/Ab result exclides the diagnisis of HIV infection in all patients that do not have history of exposure during the 18 days-6weeks before the test requested.
