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 adapted a method for dialyzable calcium from fluorometric detection by use of calcein to a more specific spectrophotometric determination with cresolphthalein complexone. The reagents are available commercially and perform satisfactorily with respect to noise level, drift, stability, and sensitivity.

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.

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

The spectral interference caused by haemoglobin in the calcium-cresolphthalein complexone reaction was investigated. The results show that the nature of the haemoglobin derivative in the reaction mixture influences the degree of interference; in turn, the derivative formed depends on the
