    PRINCIPLE

    At pH 8.5 arsenazo III (2,2-[1,8-Dihydroxy-3,6-disulpho-2,7-naphthalene-bis-(azo)] dibenzenearsonic acid) reacts with calcium ion to form a coloured complex. The intensity of colour developed is proportional to the calcium concentration in the sample.

    DIAGNOSTIC USE

    Calcium is the most abundant cation in the human body (99%) and is distributed mainly in the bones.

    High calcium levels are found in the primary and tertiary hyperparathyroidism, cancer diseases (metastatic breast carcinoma, kidney or lung, leukemia, multiple myeloma), vitamin D intoxication, high renal retention, sarcoidosis, osteoporosis, thyrotoxicosis. Low calcium levels can be attributed to renal failure, hypoparathyroidism, vitamin D deficiency, bad nutrition and bad calcium absorption.

    Single test result could not be used to make a clinical diagnosis. It should integrate clinical and laboratory data.
