Schwimmer JB et al,. SAFETY Study: alanine aminotransferase cutoff values are set too high for reliable detection of pediatric chronic liver disease. Gastroenterology 2010; 138(4): 1357-1364.
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. Icterus: No significant interference up to an I index of 60 for conjugated and unconjugated bilirubin (approximate conjugated and unconjugated bilirubin concentration: 60 mg/dL). Hemolysis: No significant interference up to an H index of 200. RBC contamination may elevate results. 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.
