| Order Code: | BILT |
| 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 whole blood from light green top tube or 1 light green microtainer
for pediatric patients
Testing
Schedule:
24 hrs/day, 7 days a week, including holidays.
Turn Around
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.
Comments:
Protect micro-specimens from unnecessary exposure to light.
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:
