Calcium Mono Reagent Kit (Arsenazo III Method) for Quantitative Determination

Calcium is an essential mineral, with approximately 99% stored in bones. The remaining calcium in serum exists in either a free ionized form or bound to proteins like albumin. Measuring serum calcium is vital because its levels are indicators for various health conditions. Increased calcium levels may suggest hyperparathyroidism, vitamin D intoxication, multiple myeloma, or certain neoplastic bone diseases. Conversely, decreased serum calcium may be observed in hypoparathyroidism, vitamin D deficiency, and certain kidney-related conditions like nephrosis and nephritis.

This reagent kit uses the Arsenazo III method to accurately measure calcium concentration. The principle is based on the reaction of calcium ions (Ca2+) with the chromogenic reagent Arsenazo III. This reaction forms a stable, blue-colored complex, and the intensity of this color is directly proportional to the calcium concentration in the sample. This simple, reliable, and sensitive endpoint method is well-suited for use in hospitals, clinics, and diagnostic laboratories to aid in the diagnosis and management of a wide range of metabolic and endocrine disorders.
