Bacterial culture will provide both a definitive diagnosis and allow determination of antibiotic sensitivities. ...Read moreSee 1 more doctor answer
1.How reliable, accurate antibodytest at 6 week post possible exposure?
2.How reliable, accurate pcr plasma test at 8 weeks even if viral load low?
HIV: The antibody test is pretty reliable, and would be reliable 6 weeks post exposure. It would theoretically be able to test positive after 5-10 days post exposure. The RT-PCR test is highly sensitive and specific but a second test should be done if the viral load was low to rule out a false positive test. A repeat RT-PCR and viral load should be redrawn and this would be a true positive if higher. ...Read more
