Serum calcium was determined by direct colorimetric method involving the complexation of serum calcium with Arsenazo
III, to form a coloured chromophore, the absorbance of which was measured at 650 nm using autoanalyser (Erbamannhein chemistry autoanalyser, Germany) using standard Erba kits 21.
Eight hundred consecutive serum specimens received in the laboratory with a request for calcium estimation were analyzed for calcium and albumin in Erba XL 640 AutoAnalyzer by Arsenazo
III method for calcium and bromocresol green in succinic acid buffer at pH 4.

The estimation of magnesium and calcium was done by Calmagite and Arsenazo
3 method with normal reference value for adult was 1.
The systemic and ultrafiltrate total calcium was detected by the arsenazo
III method, and the systemic and ultrafiltrate ionized calcium was detected using an electrolyte analyzer (GEM Premier 3000, Lexington, MA, USA).
Calcium measurements were carried out by spectrophotometry using commercial kit based on the Arsenazo
III method described by Endres and Rude in 1999 .
The same methods were used in general, except for phosphate, magnesium, and calcium (phosphomolybdate, Arsenazo
, and Arsenazo
III, respectively, in CALIPER).
Para medir la concentracion de calcio se siguio el metodo del arsenazo
III (16), La absorbancia se determino a una longitud de onda de 650 nm en un lector de microplacas (Thermo Scientific Multiskan Spectrum, Vantaa, Finlandia).
The following methods were used: calcium: Arsenazo
III dye method; uric acid: the uricase method; glucose: glucose oxidase method; aspartate aminotransferase (AST): aspartate plus the alpha ketoglutarate method; and creatine kinase (CK): the creatine phosphate method.
