Hemoglobin interference with Du Pont Automatic Clinical Analyzer procedure for calcium
Clinical Chemistry
|November 1, 1977
Hemoglobin in concentrations of approximately 2.5 g/liter or greater significantly increases values for apparent calcium in serum as determined with the Du Pont aca, an interference attributable to the 575-nm absorption band of oxyhemoglobin being uncompensated by the 577--600 nm differential absorption reading of the calcium o-cresolphthalein complexone complex.
