Rapid Plasma Reagin (RPR) with Reflex to Titer, FTA-ABS and TP-PA : 0050011

Mnemonic: RPR FTA

Ordering Recommendation: Not an optimal reflex test. Preferred test is RPR with Reflex to TP-PA (0050478).
Methodology: Semi-Quantitative Charcoal Agglutination/Semi-Quantitative Indirect Fluorescent Antibody/Semi-Quantitative Particle Agglutination
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: 0.5 mL)

Storage/Transport Temperature: Refrigerated.

Unacceptable Conditions: CSF or plasma. Contaminated, hemolyzed, or severely lipemic specimens.

Stability (collection to initiation of testing): After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year
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
0050477Treponema pallidum Antibody (FTA-ABS), Serum, IgG by IFA with Reflex to Treponema pallidum Antibody by TP-PA  
 
Test Code Components Reference Interval
 T.Pallidum Ab, IgG (FTA-ABS) Nonreactive
0050777 Treponema pallidum Antibody by TP-PA Nonreactive
0050777Treponema 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 reactive, then a titer to endpoint and FTA-ABS confirmation will be added. If FTA-ABS is inconclusive, TP-PA will be added. Additional charges apply.
CPT Code(s): 86592; if reflexed, add 86593; 86780; if reflexed, add 86780
