This test can confirm primary hyperparathyroidism from a rare inherited disorder known as Benign Familial Hypocalciuric Hypercalcemia or BFHH. Patients with this disorder have a long history of high blood calcium levels and a family history of elevated calcium levels. It is important to rule this out as these patients do not benefit from surgery. Patients with high 24-hour urine calcium levels (>100 mg/day) have primary hyperparathyroidism and those with low urine calcium levels (‹100 mg/day) have BFHH.

What are the symptoms of low calcium after thyroid or parathyroid surgery?

​

A temporary drop in the calcium level is not uncommon after thyroid and parathyroid surgeries. Symptoms can include tingling or numbness in the fingers, toes, or around the mouth. These symptoms result from increased neuromuscular irritability. In more severe cases, patients can experience muscle spasms, muscle aches or stiffness. If any of these symptoms occur, one should contact their thyroid surgeon or parathyroid doctor immediately.
