Calcium.
Methodology:
Spectrophotometric (Colorimetric)
Synonyms:

Clinical significance:
Serum calcium is involved in the regulation of neuromuscular and enzyme activity, bone metabolism, and blood coagulation. Calcium blood levels are controlled by a complex interaction of parathyroid hormone, vitamin D, calcitonin, and adrenal cortical steroids. Calcium measurements are useful in the diagnosis of parathyroid disease, some bone disorders, and chronic renal disease.
