|Plasma Separator Tube 4.5 mL|
Critical value: >12 μg/mL
Criterion: recovery plus or minus 10% of initial value at concentrations of 3 and 12 μg/mL. Icterus: No significant interference from bilirubin up to an I index of 50 (approximate bilirubin concentration: 50 mg/dL). Hemolysis: No significant interference from hemoglobin up to an H index of 1000 (approximate hemoglobin concentration: 1000 mg/dL). Lipemia: No significant interference from lipemia up to an L index of 1000. Note there is poor correlation between turbidity and triglyceride concentration. No significant interference from total protein up to 13 g/dL or rheumatoid factor up to 1200 IU/mL. As with any assay employing sheep antibodies, the possibility exists for interference by human anti-sheep antibodies in the sample, which could cause unreliable results.
