Specimen Requirements
| Fasting Required | Specimen Type | Preferred Container/Tube | Acceptable Container/Tube | Specimen Volume | Specimen Minimum Volume (allows for 1 repeat) |
Pediatric Minimum Volume (no repeat) |
|---|---|---|---|---|---|---|
| No | Plasma/Serum | Lithium-heparin Plasma Separator (PST), Serum Separator Tube (SST) | Lithium or Sodium-heparin Green Top (GTT), Red Top Tube (RTT) | 1 mL | 0.5 mL | 0.6 mL whole blood |
Collection/Processing Instructions
Samples collected in a RTT must be removed from the cells within one hour for storage or transport.
Samples collected in gel barrier tubes must be removed from the primary tube prior to transporting to Marshfield.
Do not send the primary collection tube.
Specimen Stability Information
| Specimen Type | Temperature | Time |
|---|---|---|
| Plasma/Serum | Ambient | 5 days |
| Refrigerate | 7 days | |
| Frozen | 1 year |
Rejection Criteria
Grossly icteric samples
Interpretations
Reference ranges are specific for plasma samples.
Serum samples are expected to read approximately 0.2 0.3 lower due to removal of fibrinogen during the clotting process.
