Definition. Hypocalcemia, a low bood calcium level, occurs when the concentration of free calcium ions in the blood falls below 4.0 mg/dL (dL = one tenth of a liter). The normal concentration of free calcium ions in the blood serum is 4.0-6.0 mg/dL.
Hypocalcemia most commonly results when too much calcium is lost in urine or when not enough calcium is moved from bones into the blood. Causes of hypocalcemia include the following: A low level of parathyroid hormone (hypoparathyroidism), as can occur when the parathyroid glands are damaged during thyroid gland surgery. Lack of response to a normal level of parathyroid hormone (pseudohypoparathyroidism) No parathyroid glands at birth (for example, in DiGeorge syndrome)
