Interpretive Data
 
Note
This panel is for clients in states where automatic confirmation using a treponemal test is required for all reactive RPR tests.

If RPR is reactive, then a titer to endpoint and FTA-ABS confirmation will be added. If FTA-ABS is inconclusive, TP-PA will be added. Additional charges apply.
CPT Code(s)
86592; if reflexed, add 86593; 86780; if reflexed, add 86780
