FTAS

FTA specific testing is no longer available.  UHL has replaced the FTA test with the TP-PA (treponemal pallidum particle agglutination) test.  If the provider writes FTA on the order form, testing will be forwarded to UHL for the VDRL (non-treponemal test), and if indicated, the TP-PA (confirmatory test for a positive VDRL).

Proposed algorthms for syphilis testing:

• For suspected, undiagnosed syphilis, a serum specimen should be submitted for a treponemal-specific antibody test (Syphilis IgG Antibody, by EIA).  This testing is performed by Mercy lab, Monday through Friday, 0800 cutoff.  Further confirmatory testing will be performed, when indicated (RPR and TP-PA by Mayo Med Labs).
• For determining the current disease status/evaluating response to therapy for syphilis, Mayo Med Labs RPR-Response to Therapy (RPTR) testing should be used.
