Antiphospholipid Syndrome Reflexive Panel : 2003222

Mnemonic: PHOS SYN

Methodology: Clotting/Semi-Quantitative Enzyme-Linked Immunosorbent Assay
Performed: Sun-Sat
Reported: 1-2 days
Specimen Required: Collect: Lt. blue (sodium citrate) for Lupus Anticoagulant Reflexive Panel (refer to the Specimen Handling at aruplab.com for hemostasis/thrombosis specimens handling guidelines) AND serum separator tube for cardiolipin and beta-2 glycoprotein antibodies.

Specimen Preparation: Separate platelet-poor plasma and serum from cells within 10 minutes of draw. Transport 2 mL plasma (Min: 1 mL) AND 1 mL serum (Min: 0.6 mL).

Storage/Transport Temperature: Plasma: CRITICAL FROZEN. Separate specimens must be submitted when mulitiple tests are ordered.
Serum: Refrigerated.


Unacceptable Conditions: For Lupus Anticoagulant Reflexive Panel (Plasma): Serum and non-sodium citrate plasma.
For cardiolipin and beta-2 glycoprotein antibodies (Serum): Plasma and other body fluids, heat-inactivated, hemolyzed, lipemic, or contaminated specimens.


Stability (collection to initiation of testing): For Lupus Anticoagulant Reflexive Panel (Plasma): Ambient: 4 hours; Refrigerated: 24 hours; Frozen: 1 week;
For cardiolipin and beta-2 glycoprotein antibodies (Serum): Ambient: 48 hours; Refrigerated: 2 weeks; Frozen 1 year (avoid repeated freeze/thaw cycles).

Interpretive Data: See individual components.
Note: If PTT and dRVVT are normal, no further testing is performed. If PTT is abnormal, Thrombin Time is added. If Thrombin Time is normal, PTT 1:1 mix is added.  If Thrombin time is abnormal, Reptilase Time is added. If Reptilase Time is abnormal, PTT 1:1 mix is added. If Reptilase Time is normal, PTT Heparin Neutralization is added. If PTT Heparin Neutralization is abnormal, PTT 1:1 mix is added.  If PTT 1:1 mix is abnormal, Platelet Neutralization procedure is added. If dRVVT is abnormal, dRVVT 1:1 mix is added. If dRVVT 1:1 mix is abnormal, dRVVT confirmation is added. If Platelet Neutralization procedure and dRVVT confirmation are normal or if one is normal and the other not done, Hexagonal Phospholipid Neutralization is added. Additional charges may apply.
CPT Code(s): Anti-Cardiolipin Antibody G/M: 86147 x2; Beta-2 Glycoprotein I, G/M: 86146 x2; 85610 Prothrombin time (PT); 85730 Partial Thromboplastin Time (PTT); 85613 dRVVT. If PTT is abnormal, add 85670 Thrombin Time. If Thrombin time is abnormal, add 85635 Reptilase Time. If Reptilase Time is normal, add PTT Heparin Neutralization 85730 and 85525. If PTT Heparin Neutralization is abnormal, add 85732 PTT 1:1 mix. If PTT 1:1 mix is abnormal, add 85597 Platelet neutralization procedure (PNP). If dRVVT is abnormal, add 85613 dRVVT 1:1 mix. If dRVVT 1:1 mix is abnormal, perform 85613 dRVVT confirmation. If PNP and dRVVT conf are normal, add 85598 Hexagonal Phospholipid Neutralization.
