The reasons for the non-linearity of the standard curve for the calcium-cresolphthalein complexone reaction have been investigated. Calcium forms both 1:1 and 2:1 complexes with cresolphthalein complexone; at low calcium concentrations the 1:1 complex predominates and causes non-linearity. At high

We describe the measurement of total calcium and magnesium in serum with an automated microcomputer-controlled stopped-flow analyzer. The calcium method is based on the cresolphthalein complexone procedure, with 2-amino-3-methyl-1-propanol as the alkalinizing agent. The assay, performed on 60-fold prediluted samples

We describe an automated method for calcium assay, for use with the Cobas-Bio centrifugal analyzer. Calcium is reacted with cresolphthalein complexone and the absorbance of the calcium--dye complex at 575 nm is measured. EDTA is then added to break up

Severe hypocalcemia may require prompt intervention to avoid life-threatening consequences. We report a case in which a 78-year-old man had a critically low serum calcium level measured with use of standard colorimetric assay after gadodiamide administration during magnetic resonance angiography.

An automated calcium method based on o-cresolphthalein complexone chemistry and designed to be used in conjunction with the Beckman ASTRA systems (Beckman Instruments, Inc., Brea, CA) was evaluated. Day-to-day reproducibility studies yielded coefficients of variation ranging from 1.2 to 3.1%.
