| Plasma Separator Tube 4.5 mL |
Alternate Collection Media:
Call laboratory for additional acceptable specimen collection
containers.
Minimum:
3 mL; light green top or ONE Microtainer®
Testing Schedule:
24 hrs/day, 7 days a week, including holidays.
Turn Around Time:
1 hour (upon receipt in laboratory)
Reference Range:
Adult Reference Range: 3.4 - 4.8 g/dL Pediatric Reference Ranges: 0 - 4 days = 2.8 - 4.4 g/dL 4 days - 14 years = 3.8 - 5.4 g/dL 14 years - 18 years = 3.2 - 4.5 g/dL
Test Limitations:
Icterus: No significant interference up to an I index of 60 (approximate conjugated and unconjugated bilirubin concentration: 60 mg/dL). Hemolysis: No significant interference up to an H index of 1000 (approximate hemoglobin concentration: 1000 mg/dL). Lipemia (Intralipid): No significant interference up to an L index of 550. There is poor correlation between turbidity and triglycerides concentration. In very rare cases gammopathy, in particular type IgM (Waldenstrom's Macroglobulinemia), may cause unreliable results.
