Normal: < 150 mg/dL Borderline High: 150-199 mg/dL High: 200-499 mg/dL Very High: > or = 500 mg/dL To convert triglyceride values to mm/L, divide by 88.6.
This test is also performed in the Iowa River Landing (IRL) clinical laboratory (for specimens drawn at that site).
Serum/Plasma Icterus: Significant negative interference can occur with I index above 10 for conjugated bilirubin and above 35 for unconjugated bilirubin (approximate conjugated bilirubin concentration of 10 mg/dL or approximate unconjugated bilirubin concentration of 35 mg/dL). Hemolysis: No significant interference up to an H index of 700 (approximate hemoglobin concentration: 700 mg/dL). Lipemia (Intralipid): The L index correlates with sample turbidity and not to triglycerides level. Serum samples having extremely elevated triglycerides (greater than 3000 mg/dL) can produce a normal result.* High concentrations of unesterified glycerol in the sample can produce falsely elevated results. This can occur in rare inborn errors of glycerol metabolism (e.g., glycerol kinase deficiency). In very rare cases gammopathy, in particular type IgM Walderstroms macroglobulinemia, may cause unreliable results. *Shephard MDS, Whiting MJ. Clin Chem. 1990;36(2):325-329.
