Urinary calcium levels are an indication of calcium passed from the body. It generally reflects dietary intake, rate of calcium absorption via the intestines, and re-absorption of calcium into bones. Under normal conditions, the slight increase in absorption occurring from an increase in dietary calcium intake will generally be reflected in an increase in urinary excretion. Urinary calcium is used primarily to assess parathyroid function and the effects of Vitamin D levels. However, parathyroid conditions and associated Vitamin D levels are not the only use for determining urine calcium. Various clinical states that correlate with increased urine calcium levels are as follows: primary hyperparathyroidism, presence of kidney stones, cancers that may have spread to bone, sarcoidosis, Paget's disease, severe hyperthyroidism, dehydration, and kidney disease. Further, increased levels of urine calcium attributed to unknown reasons are termed idiopathic hypercalciuria. Decreased urine calcium is observed with low dietary calcium and / or Vitamin D intake, poor absorption via the intestines, kidney disease, and conditions of the parathyroid glands, such as hypoparathyroidism.

Collect 10 mL random urine in a plastic; screw-capped container and
adjust pH to <3.0 6N HCl (Minimum: 2mL). Aliquot urine specimens
and send at room temperature to the laboratory.
