What is Calcium?
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, transmitting signals in nerve cells, and muscle contraction.
Why should you test Calcium levels?
A calcium test can be useful for determining whether there is a high or low calcium level in the blood, which can indicate various health issues. Testing calcium may be especially important for people with symptoms of a calcium deficiency or excess, or for those who suffer from conditions that affect calcium absorption.
What does it indicate?
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.
What does a high calcium level mean?
A high calcium level, or hypercalcemia, may indicate hyperparathyroidism (overactive parathyroid glands), or excessive intake of calcium or vitamin D.
What does a low calcium level mean?
A low calcium level, or hypocalcemia, may indicate a deficiency of vitamin D, kidney failure, or hypoparathyroidism (underactive parathyroid glands). It can also occur with pancreatitis or certain medications.
