A member asked:
What is a tpha quantitative blood test? can this test detect latent stage syphilis?
A doctor has provided 1 answer
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. If you have had negative results on one of these plus the TPHA, you can be 100% certain you don't have syphilis and probably never did.
