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 | 0.3 mL | 0.3 mL serum or plasma from 0.6 mL whole blood |
Collection/Processing Instructions
Bilirubin is light sensitive. Protect samples from light.
Samples collected in a SST or RTT must be removed from cells within one hour for storage or transport.
DBIL can only be U-Haved/add-on from a previously collected sample if requested within 24 hours of the original collection, or if the sample has been protected from light.
Specimen Stability Information
| Specimen Type | Temperature | Time |
|---|---|---|
| Plasma/Serum | Ambient | 1 day |
| Refrigerate | 2 days | |
| Frozen | 3 months |
Rejection Criteria
Grossly hemolyzed
Interferences
Hemolysis falsely decreases DBIL result.
