Your doctor will begin by reviewing your medical history. They’ll then do a physical examination to check for symptoms such as dry skin, muscle spasms, and hair loss.
Your doctor will order blood tests to check the levels of the following in your blood:
calcium
phosphorus
magnesium
PTH
Additional tests include the following:
Your doctor may test your urine for calcium to determine if excess levels of calcium are being secreted in the urine.
An electrocardiogram (EKG) measures the electrical activity in your heart. The information from this test can tell your doctor if you have an abnormal heart rhythm, which can be caused by calcium deficiency.
X-rays and bone density tests can help your doctor determine if low calcium levels have affected your bones.
