Interference of intravenous lipid emulsion with the determination of calcium in serum
Abstract:
A lipid emulsion in concentrations similar to those attained after therapeutic dosages were found to interfere with the determination of total serum calcium measured by a fluorometric method. Calcium results determined by atomic absorption and by fluorometry at different concentrations of lipid emulsion were compared. When lipid concentrations were less than 100 mg/dl, centrifugation was effective in eliminating the artifactural elevation in total serum calcium. Possible reasons for the observed differences are discussed.
