Hi every body
I have a friend who has been given HIV "borderline positive" twice by Abbott's MEIA technique, once three years ago when he went to donate blood and then last week. After both tests for the sake of confirmation he tried ELISA from other manufacturers and even Immunochromatography from Abbott (determine) and he is negative on all accounts. He has no such history. He is as strong and healthy as three years ago. his blood profile and other routine biochemical parameters are normal. He once had herpes viral infection several years ago.
My question is that Is possible to get false positives by MEIA technique? If there is some interference then what it could be? three years ago PCR test was also negative.
