Can an HIV antibody screening test be positive but the western blot negative?

Yes: There are 2 reasons for this kind of result: (1) a false positive, or (2) early infection before seroconversion. In someone at low risk for HIV without symptoms, another negative WB in 1 month means there's no infection. In someone at risk or with symptoms of acute infection, a viral load can be helpful. The new 4th generation antigen/antibody tests will eliminate this problem. ...Read more

When the hiv test is conclusive?.what causes repeated perianal fungal infection?last hiv test 14monthes postexposure.is negative?

No worries: Every HIV test that exists, anywhere in the world, is conclusive by 3 months. The most commonly used tests are conclusive by 4-8 weeks.

Entirely healthy people often get perianal fungal infections; it's not a sign of HIV. ...Read more

Can a positive Lyme disease western blot strip test be mistaken for another disease?

Can a positive Lyme disease western blot strip test be mistaken for another disease?

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.

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
