Prealbumin
Label Mnemonic: PREALB
Epic Lab Code: LAB115
Downtime Form: A-1a General Laboratory Requisition
Chemistry
6240 RCP
356-3527
Specimen(s):
Plasma
Collection Medium:
Plasma Separator Tube 4.5 mL
Alternate Collection Media:
Call laboratory for additional acceptable specimen collection containers.
Minimum:
3 mL whole blood in light green top tube 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:
18-45 mg/dL (adults). Values for pediatric patients vary with age.
Test Limitations:
Criterion: Recovery within plus or minus 10% of initial values. 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 100. There is poor correlation between turbidity and triglycerides concentration. Rheumatoid factors less than 400 IU/mL do not interfere. No high-dose hook effect was found up to prealbumin concentrations of 250 mg/dL. Falsely decreased results may be observed in samples from patients with monoclonal gammopathies of the IgM type.
Methodology:
Immunoturbidimetric
