The TP-PA test is a confirmatory treponemal test used to aid in the diagnosis of syphilis in the context of a positive non-treponemal (lipoidal antigen) assay. It is not intended to be used as a standalone test for diagnosis. For algorithm based syphilis testing, please see test code 90349 Syphilis Antibody Cascading Reflex (reverse) or test code 36126 RPR (Diagnosis) with Reflex to Titer and Confirmatory Testing (traditional).
