ARUP's Laboratory Test Directory

Rapid Plasma Reagin (RPR) with Reflex to Titer : 0050471

Mnemonic: RPRT

Ordering Recommendation: CDC recommended screening test for syphilis. May use to confirm reactive treponemal test (eg, EIA, CIA) if using so-called reverse algorithm testing. Preferred test for monitoring treatment response in established syphilis.
Methodology: Semi-Quantitative Charcoal Agglutination
Performed: Sun-Sat
Reported: Within 24 hours
Specimen Required: Collect: Serum separator tube.

Specimen Preparation: Separate serum from cells ASAP or within 2 hours of collection. Transfer 0.5 mL serum to an ARUP Standard Transport Tube. (Min: 0.25 mL) 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
 Rapid Plasma Reagin (RPR) Effective May 21, 2012
RPR (+) = Reactive
RPR (-) = Nonreactive
 Rapid Plasma Reagin (RPR) Titer < 1:1

Note: If RPR is reactive, then a titer will be added. Additional charges apply.
CPT Code(s): 86592 RPR; if reflexed, add 86593 RPR titer
