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

Mnemonic: RPR PAN

Methodology: Semi-Quantitative Charcoal Agglutination/Semi-Quantitative Particle Agglutination (PA)
Performed: Sun-Sat
Reported: 1-4 days
Specimen Required: Collect: Serum separator tube.

Specimen Preparation: Separate serum from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.25 mL) Do not freeze. Also acceptable: Plasma, if testing is completed within 48 hours of collection.

Storage/Transport Temperature: Refrigerated.

Unacceptable Conditions: CSF or other body fluids.

Stability (collection to initiation of testing): After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
Reference Interval:
 
Test Number Components Reference Interval
 Treponema pallidum (RPR) RPR (+) = Reactive
RPR (weak +) = Weakly reactive
RPR (-) = Nonreactive
 Treponema pallidum (RPR) Titer < 1:1
 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. Additional charges apply.
CPT Code(s): 86592 RPR; if reflexed, add 86593 RPR titer and TP-PA 86780
Cross References: Rapid Plasma Reagin (RPR) with MHA-TP Confirmation, RPR with MHA-TP Confirmation
