Acetaminophen concentrations greater than 150 μg/mL at four hours after ingestion or greater than 40 μg/mL at 12 hours after ingestion are often associated with toxicity. Critical value: >40 μg/mL
Lipemia: No significant interference up to an L index of 400 (approximate triglycerides concentration: 800 mg/dL). Note there is poor correlation between turbidity and triglyceride concentration.
Icterus: Icterus can cause positive interference with the acetaminophen assay. Testing is cancelled with an icteric index of 30 or greater.
