Treponema pallidum (Rapid Plasma Reagin) with Reflex to Titer & FTA-ABS Confirmation : 0050011

Mnemonic: RPR FTA

Methodology: Refer to individual components
Performed: Sun-Sat
Reported: 1-4 days
Specimen Required: Collect:  One 4 mL serum separator tube.

Storage/Transport Temperature:  1 mL serum at 2-8°C.  (Min: 0.5 mL)  Submit specimen in an ARUP Standard Transport Tube.

Remarks:  Separate serum from cells ASAP.

Unacceptable Conditions:  Plasma or CSF.  Severely lipemic, contaminated, or hemolyzed specimens.

Stability (collection to initiation of testing):  After separation from cells: Ambient: 2 days; Refrigerated: 2 weeks; Frozen: 1 year
Reference Interval:
 
Test Number Components Reference Interval
 Treponema pallidum (RPR) Nonreactive
 Treponema pallidum (RPR) Titer < 1:2
0050477Treponema pallidum Antibody (FTA-ABS), Serum, IgG by IFA with reflex to Treponema pallidum Antibody by TP-PA Nonreactive

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 weakly reactive or reactive, then a titer to endpoint and FTA-ABS confirmation will be added.
CPT Code(s): 86592 RPR; if reflexed, add 86593 RPR titer; 86780 FTA
