Albumin
Order Code: ALB
Order Form: Laboratory Requisition
Specimen:
Plasma
Collection Medium:
Plasma Separator Tube
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 1000 (approximate triglycerides concentration: 2000 mg/dL).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. Reference Glick MR, Ryder KW, Jackson SA.
