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.

Patient must have fasted for 12 hours. Please print, complete and submit the Advance Beneficiary Notice (ABN) along with the Laboratory Requisition before shipping the specimen.

Serum/Plasma Icterus: Significant negative interference can occur with I index above 10 for conjugated bilirubin and above 27 for unconjugated bilirubin (approximate conjugated bilirubin concentration of 10 mg/dL or approximate unconjugated bilirubin concentration of 27 mg/dL). Hemolysis: No significant interference up to an H index of 500 (approximate hemoglobin concentration: 500 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.* Prior to being tested for triglycerides, dilute grossly lipemic sera 1 part serum to 5 parts 0.9% NaCl and multiply the results by 6. Not all samples having this level of triglycerides are grossly lipemic. 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.
