Exams and Tests
- The diagnosis of hyperparathyroidism is made by blood tests. If the results of the blood tests reveal that the calcium levels in the blood are elevated, and the blood PTH levels are also inappropriately high for the serum calcium, the diagnosis of hyperparathyroidism can be confirmed.
- While there can be other causes of high blood calcium (hypercalcemia), this finding combined with the high PTH level confirms the diagnosis.
- A 24-hour urine examination may also be ordered to confirm an increase of calcium in urine.
- X-rays of bone structures may reveal fractures and other changes in bone.
- Abdominal imaging may also reveal evidence of stones in the kidney, ureters, or bladder.
