Includes
Panel components: Cardiolipin antibodies IgG and IgM, Beta-2 glycoprotein antibodies IgG and IgM, PT, PTT, Thrombin Time, Anti-Xa, Fibrinogen (if indicated), dRVVT and Silica Clotting Time Screen (SCT), dRVVT and SCT confirmation (if indicated), dRVVT and SCT mixing studies.

This test includes a Pathologist interpretation.


Preferred Specimen
  • 2 Blue tubes (Sodium Citrate)
  • 1 Gold tube (gel-separator)


Minimum Volume
1 mL plasma
1 mL serum


Other Acceptable Specimens
None


Instructions
This test requires two sample types:
  • Serum:  Centrifuge for complete separation of serum and red cells.  Refrigerate until tested.
  • Plasma:  Tube MUST be full for proper whole blood to anticoagulant ratio.  Invert tube "end-to-end" to prevent clotting.  Centrifuge to obtain platelet-poor plasma.  Refer to the document Obtaining A Platelet-Poor Sample below.



Transport Temperature
Plasma: Must be frozen
Serum:  Refrigerate


Specimen Stability
  • Plasma:  Frozen plasma is stable up to 2 weeks
  • Serum:  2-8°C up to 7 days


Reject Criteria (Eg, hemolysis? Lipemia? Thaw/Other?)
The following conditions will be rejected:
  • Refrigerated plasma samples that are >4 hours from collection
  • Clotted samples
  • Grossly hemolyzed samples


Methodology
Clot Detection and Multiplex Flow Immunoassay

Setup Schedule
T, Th only


Report Available
Within 24 hours of the day tested.
