1 hour (upon receipt in laboratory)
Reference Range:
30-200 mg/dL
Test
Limitations:
Rheumatoid factors less than 250 IU/mL do not interfere.
A high-dose hook effect may occur at haptoglobin concentrations above 1200 mg/dL.
Hemolysis: No significant interference up to an H index of 150 (approximate hemoglobin concentration: 150 mg/dL).
Lipemia: No significant interference up to an L index of 200 (approximate triglycerides concentration: 400 mg/dL). Note there is poor correlation between turbidity and triglyceride concentration.
Icterus: No significant interference up to an I index of 60 (approximate conjugated and unconjugated bilirubin concentration: 60 mg/dL).
