Test
Limitations:

Criterion: Recovery within plus or minus 10% of initial values at a 
lipase activity of 50 U/l.

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 500 
(approximate hemoglobin concentration: 500 mg/dl)

Lipemia (Intralipid): No significant interference up to an L index of 
1000 (approximate triglycerides concentration: 2000 mg/dl). There is 
poor correlation between turbidity and triglycerides concentration.
