Calcium Urine is a laboratory test that measures the amount of calcium present in a urine sample. It helps assess how the kidneys handle and excrete calcium and provides information about calcium metabolism. The test is needed to investigate abnormal calcium levels, evaluate the risk of kidney stones, and support the assessment of conditions affecting the parathyroid glands, kidneys, bones, or vitamin D metabolism.
Urinary calcium reflects the amount of calcium eliminated by the kidneys. Abnormal levels may provide clues about calcium balance and certain kidney or hormonal conditions.
High urinary calcium, known as hypercalciuria, may occur due to certain metabolic or hormonal disorders, dietary factors, medications, or increased calcium loss through the kidneys.
Low urinary calcium may occur with reduced calcium intake or absorption, vitamin D deficiency, certain hormonal conditions, or other metabolic and kidney-related disorders.
Yes. Excess calcium in urine can contribute to the formation of calcium-containing kidney stones, especially when other factors that promote stone formation are present.
