Tests and diagnosis

By Mayo Clinic Staff

Medical history

A doctor who suspects hypoparathyroidism begins by taking a medical history and asking about your symptoms, such as muscle cramps or tingling of your toes, fingers or lips. He or she will want to know whether you've had recent surgeries, particularly operations involving the thyroid gland or your neck.

Physical exam

Next, your doctor will conduct a physical examination, looking for signs that suggest hypoparathyroidism, such as facial muscle twitching.

Blood tests

You'll also have blood tests, and the following findings may indicate hypoparathyroidism:

  • A low blood-calcium level
  • A low parathyroid hormone level
  • A high blood-phosphorus level
  • A low blood-magnesium level

Your doctor may also order a urine test to determine whether your body is excreting too much calcium.

In diagnosing children, doctors check to see whether tooth development is normal and whether they have met developmental milestones.
