Intended Use

The Randox Laboratories Limited Calcium Test Kit is an in vitro diagnostic reagent for the quantitative determination of calcium in human serum. This method is based on the interaction of calcium with Arsenazo III to form a coloured complex which can be measured at 650nm. The intensity of the final colour is directly proportional to the calcium concentration. Measurements of calcium are used in the diagnosis and treatment of parathyroid disease, malignant diseases with and without bone involvement, chronic renal failure and a variety of bone diseases. This test kit must be used by suitably qualified laboratory personnel under appropriate laboratory conditions.

Device Story
