Calcium Test (Serum)

Calcium test is a diagnostic test that measures the level of calcium in a person's blood. Calcium is an important mineral that plays a vital role in various bodily functions, including the functioning of the nervous system, muscle contraction, and bone health. The calcium test is usually ordered as part of a routine blood workup, or when a person is suspected of having a condition that affects calcium metabolism, such as hyperparathyroidism or kidney disease.

The test involves taking a small sample of blood from the patient's vein, and then measuring the amount of calcium present in the blood. Abnormal levels of calcium in the blood can indicate various medical conditions, such as hypercalcaemia (elevated calcium levels) or hypocalcaemia (low calcium levels). Treatment for these conditions will depend on the underlying cause and may involve medications, lifestyle changes, or other interventions.
