Treponema pallidum (Rapid Plasma Reagin) with Reflex to Titer & TP-PA Confirmation : 0050478

Mnemonic: RPR PAN

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

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

Pediatric Collection/Transport:  0.25 mL serum at 2-8°C.

Remarks:  Separate serum from cells ASAP. Plasma is also acceptable if testing is completed before the specimen is 48 hours old.  Do not freeze.

Unacceptable Conditions:  CSF and other body fluids.

Stability:  After separation from cells: Ambient: 2 days; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
Reference Interval:
 
Test Number Components Reference Interval
 Treponema pallidum (RPR) Nonreactive
 Treponema pallidum (RPR) Titer < 1:2
 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 TP-PA confirmation will be added.
CPT Code(s): 86592 Treponema pallidum screen; if reflexed, add 86593 Treponema pallidum titer and 86781 Treponema pallidum (MHA) confirmation
