The culture is the "gold standard" but you will need to wait for it. It might turn out be a cousin of TB and that too will grow out of culture. Stay on TB meds until they are certain of the AFB positive organism. ...Read more

Most of the time, when positive, it highly suggests HIV infection. However, in rare instances, there can be false positive tests, which mean that a positive test may represent something else, not HIV. Thus, the best test for HIV is a standard HIV antibody test. ...Read moreSee 1 more doctor answer
2 false pos ELISA HIV tests, all 1 1/2 years post exposure. Neg western blot, ifa, naat and 2 neg oraquick home tests. What is my HIV status? Help!
Likely negative: There is typically a "window" of 3-6 months after exposure where you could be HIV positive but test negative. Since you didn't get your testing until well after that, i'd say the confirmatory tests (western blot, ifa) are what you should go by. The elisa is very sensitive and can have false positives- that's why we rely on the confirmatory tests. I would consider your status to be negative. ...Read more

Spinal fluid culture: To diagnose bacterial meningitis, typically, a spinal tap is done to remove a small amount of cerebrospinal fluid that surrounds the spinal cord and brain.

It may also be cultured for viruses and that can take 7 day. ...Read more
