Preferred Specimen
- 2 Blue tubes (Sodium Citrate)
- 1 Gold tube (gel-separator)
Minimum Volume
1 mL plasma
1 mL serum
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
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.
