Will STDs be detected in urinalysis, syphilis serology tests?

What is a tpha quantitative blood test? Can this test detect latent stage syphilis?

Yes it can: The TPHA test (Treponema pallidum hemagglutination) is a confirmatory test for syphilis. Usually it is done only after a positive screening test, such as the VDRL, RPR, or an EIA test.

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

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

Acth stimulation test results accurate?

Lab Error: I would chalk this up to lab error, but in my patients we do not leave it there. There is a much better and more valid test to be done called a western blot test for herpes. This definitive test should have already been offered to you so that you can know for a fact whether you have herpes or not. ...Read more
