血钙过低症通常由甲状腺或甲状旁腺手术时损及甲状旁腺所引起。偶尔,持久性血钙过低症也可见于一些罕见的疾患如:特发性甲状旁腺机能衰竭、甲状旁腺浸润及假性甲状旁腺机能减退等。血钙过低症也发生于严重维生素D缺乏与镁缺乏所引起的甲状旁腺激素(PTH)分泌的可逆性衰竭。血钙过低症的原因急性输注乙二胺四醋酸(EDTA)或乙二醇双氨乙基乙醚四醋酸(EGTA),由于血中形成不能解离的钙复合物,可使血浆钙水平降低(其血浆总钙水平未变)。降钙素(CT)和光辉
Hypercalcaemia is usually caused by damage to the parathyroid glands when thyroid or parathyroid surgery is performed. Occasionally, persistent hypocalcaemia can also be seen in rare diseases such as idiopathic parathyroid failure, parathyroid invasion and hypoparathyroidism. Hypocalcemia also occurs in the reversible failure of parathyroid hormone (PTH) secretion caused by severe vitamin D deficiency and magnesium deficiency. Causes of hypocalcaemia Acute infusion of ethylenediaminetetraacetic acid (EDTA) or ethyleneglycol bisaminoethylethertetraacetic acid (EGTA), due to the formation of calcium can not be dissociated in the blood of calcium complexes, can make plasma calcium levels Lower (its total plasma calcium level unchanged).
