A calcium blood test measures the amount of calcium in your blood. Too much or too little calcium in your blood may be a sign of a wide range of medical conditions, such as bone disease, thyroid disease, parathyroid disorders, kidney disease, and other conditions.
A blood calcium test is used to check your general health. It's also used to help diagnose or monitor many medical conditions, including those that affect your bones, kidneys, digestive system, thyroid, and parathyroid glands.
