The parathyroid glands regulate the calcium level in the blood. In hyperparathyroidism, the serum calcium level will be elevated. Parathyroid hormone levels may be high or normal but not low. The body will lower the level of vitamin D in an attempt to lower calcium. Urine calcium may be elevated, with calcium spilling over from elevated serum levels. This may cause renal stones.
