Hello, Thanks for the query to H.C.M. Forum. Let me explain few facts which may be important for you. As both tests are for Syphilis . 1 Nontreponemal i. e more sensitive , less specific. Can be negative in primary syphilis in up to 30 % but always positive in secondary syphilis . fourfold changes are considered significant. 2 Treponemal test ( TPHA) directed against specific treponemal antigens.More specific than nontreponemal test & mainly used for confirmation. Now very clearly you have understand the meaning of these two tests. Hope I have answered your question. If further any question I will help. Dr. HET
