I have antibodies that produce positive ANA screening and false positive syphilis screening. What does that mean?

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

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.
