Bilirubin, Total
Order Code: BILT
Epic Lab Code: LAB50
Order Form: A-1a General Lab or Epic Req
Chemistry
6240 RCP
356-3527
Specimen:
Plasma
Collection Medium:
Plasma Separator Tube
Alternate Collection Media:
Call laboratory for additional acceptable specimen collection containers.
Minimum:
3 mL whole blood from light green top tube or 1 light green microtainer for pediatric patients
Specimen Instructions:
Protect micro-specimens from unnecessary exposure to light.
Testing Schedule:
24 hrs/day, 7 days a week, including holidays.
Analytic Time:
1 hour (upon receipt in laboratory)
Reference Range:
0-2 days: 0.2-6.0 mg/dL 2-3 days: 0.2-7.0 mg/dL 3-11 days: 0.2-10.0 mg/dL 11-31 days: 0.2-1.0 mg/dL Adult and Children: 0.2-1.0 mg/dL Critical value: >10.0 mg/dL for first 24 hrs >13.0 mg/dL for 1-30 days Refer to: Bilirubin Nomogram for designation of risk for newborns.
Test Limitations:
Criterion: recovery plus or minus 0.4 mg/dL (6.8 umol/l) or 10% (whichever is greater) of initial values. Plasma 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. Indican: No significant interference from indican up to levels of 10 mg/dL. Results from certain multiple myeloma patient samples may show a positive bias in recovery. Not all multiple myeloma patients show the bias and the severity of the bias may vary between patients.
Methodology:
Spectrophotometric
CPT Code:
82247
