This test is also performed in the Iowa River Landing (IRL) clinical laboratory (for specimens drawn at that site).
Criterion: Recovery within plus or minus 10% of initial values. Plasma 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 1000 (approximate hemoglobin concentration: 1000 mg/dL) Lipemia (Intralipid): No significant interference up to an L index of 1000. There is poor correlation between turbidity and triglycerides concentration. Great care must be taken to prevent ammonia contamination of the specimens to be analyzed for urea/urea nitrogen.
