Hi,

TPHA titer has no value in interpreting. The significance is whether it is reactive or nonreactive. That is all. Once reactive, it will remain reactive forever. It has no quantifying value, just a confirmative test for syphilis.

Take care. Hope I have answered your question. Let me know if I can assist you further.
