Critical value (1 month-adults): <50 mg/dL and >450
The Expert Committee on the Diagnosis and Classification of Diabetes

mg/dL but less than 126 mg/dL. (Diabetes Care 28 (Suppl 1) S41, 2005)
Pediatric Reference Ranges:
Age Range Units
0-1 month 40-99 mg/dL
1 month-adult 65-99 mg/dL
Critical value (0-1 month): <40 mg/dL and >300

Test
Limitations:
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 1000
(approximate hemoglobin concentration 1000 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.
