Antiphospholipid Syndrome Reflexive Panel : 2003222

Mnemonic: PHOS SYN

Ordering Recommendation: Preferred initial panel for strong suspicion of antiphospholipid syndrome (APS).
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: Transport 2 mL platelet poor plasma. (Min: 1 mL) AND 1 mL serum (Min: 0.6 mL) in two separate ARUP Standard Transport Tubes.

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.
