Diagnosis

A doctor who suspects hypoparathyroidism will take a medical history and conduct a physical exam.

Blood tests

These findings on blood tests might indicate hypoparathyroidism:

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

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