|Additional information||To convert mg/dL to mmol/L (SI units) multiply by 0.0113.
Increased levels of bilirubin may artifactually decrease the result.
Patients with levels > 1000 mg/dL (> 11.3 mmol/L) are prone to develop pancreatitis. Values above 2000 mg/dL will be phoned the same day Monday-Friday 0800-1500 or next weekday.
The sera of patients with triglycerides > 1000 mg/dL are lipemic and at high levels will artifactually lower the assay results for many water-soluble constituents, e.g., electrolytes. A mathematical correction can be applied to electrolyte measurements to obtain the true value (Steffes MW, Freier EF: J Lab Clin Med 1976;88:683):
Corrected value = (0.994 + [0.00021 x Trig conc]) x measured analyte conc.
