Specimen:
Plasma
Collection Medium:
 |
| Plasma Separator Tube |
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.
Analytic 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 500
(approximate hemoglobin concentration: 500 mg/dl).
Lipemia (Intralipid®): No significant interference up to an L index of
200 (approximate triglycerides concentration: 400 mg/dl). There is poor
correlation between turbidity and triglycerides concentration.
Lipemia (Pentex Triglyceride Supertrate [Avian]): No significant
interference up to 1730 mg/dl.
Rheumatoid factors less than 100 IU/ml do not interfere.
No high-dose hook effect was found up to prealbumin concentrations
of 260 mg/dl.
Falsely decreased results may be observed in samples from patients with
monoclonal gammopathies of the IgM type.
