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. Plasma Icterus: No significant interference up to an I index of 60. Hemolysis: Significant positive interference at an H index greater than 300 (approximate hemoglobin concentration: 300 mg/dL). NOTE: This interference results from inorganic phosphates produced by the action of phosphatases on organic phosphates, both of which are released from the red cell upon hemolysis (2). Lipemia (Intralipid): No significant interference up to an L index of 800. There is poor correlation between turbidity and triglycerides concentration. Drugs: No interference was found at therapeutic concentrations using common drug panels.
