Test ID | Reporting Name | Available Separately | Always Performed |
---|---|---|---|
RRPRS | RPR Screen w/ Reflex to Titer, S | No | No |
RTPPA | Syphilis Ab, TP-PA, S | Yes, (Order TPPA) | No |
RRPRQ | RPR Titer, S | No | No |
Testing Algorithm
If the syphilis IgG result is reactive or equivocal, then the rapid plasma reagin (RPR) screen will be performed at an additional charge.
If the RPR screen is positive, then the RPR titer will be performed at an additional charge.
If the RPR screen is negative, then syphilis antibody Treponema pallidum particle agglutination testing will be performed at an additional charge.
