Calcium is a mineral that is crucial for the structure and maintenance of bones and teeth. It also plays an important role in blood clotting, the transmission of signals in nerve cells, and muscle contraction.
A calcium test can be useful for determining whether there is a too high or too low calcium level in the blood, which may indicate various health problems. Testing calcium can be particularly important for people with symptoms of calcium deficiency or excess, or for those suffering from conditions that affect calcium absorption.
The calcium level in the blood can be an indicator for a range of conditions, including osteoporosis, thyroid problems, and kidney diseases. It can also point to the effectiveness of calcium supplements or the impact of certain medications on calcium metabolism.
A high calcium level, or hypercalcemia, may indicate hyperparathyroidism (overactive parathyroid glands), certain types of cancer, or excessive intake of calcium or vitamin D.
A low calcium level, or hypocalcemia, may indicate a vitamin D deficiency, kidney failure, or hypoparathyroidism (underactive parathyroid glands). It can also occur with pancreatitis or certain medications.
