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 value. Hemolysis interferes due to AST activity from erythrocytes (index of 50). Icterus: No significant interference up to an I index of 60 (approximate conjugated and unconjugated bilirubin concentration: 60 mg/dL). Lipemia (Intralipid): No significant interference up to an L index of 250 (approximate triglycerides concentration: 500 mg/dL). There is poor correlation between turbidity and triglycerides concentration. Lipemia may cause absorbance flagging as a result of an absorbance increase. Reference Glick MR, Ryder KW, Jackson SA.
