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.
Analytic Time:
1 hour (upon receipt in laboratory)
Reference Range:
50-100 mcg/mL
Critical value: >150 mcg/mL
Test
Limitations:
Criterion: recovery plus or minus 10% of initial value at
concentrations of 50 mcg/mL and 100 mcg/mL.
Icterus: No significant interference from bilirubin up to an I index of
30 (approximate bilirubin concentration: 30 mg/dL).
Hemolysis: No significant interference from hemoglobin up to an H index
of 500 (approximate hemoglobin concentration: 500 mg/dL).
Lipemia (Intralipid): No significant interference up to an L index of
