一般所见的高钙血症有许多病理学原因和潜在机制,鉴别诊断比较困难,因为尚无某一项实验或系列实验能区别恶性与非恶性原因。由于高度灵敏的放免法测定甲状旁腺素(PT-H),目前已能阐明 PTH 在非恶性病变高钙血症中的作用,此项测定能合理地确定原发性甲旁亢,患者循环 PTH 浓度呈与离子钙浓度相关的升高,而且通常都高于参考范围。相反,体液因子在伴有恶
Generally seen in hypercalcemia there are many pathological reasons and underlying mechanisms, differential diagnosis more difficult, because there is no experiment or a series of experiments to distinguish between malignant and non-malignant causes. Due to the highly sensitive radioimmunoassay for the determination of parathyroid hormone (PT-H), the role of PTH in non-malignant hypercalcaemia has now been elucidated. This assay can reasonably determine primary hyperparathyroidism, patient circulation PTH concentrations show increases associated with ionized calcium concentrations, and are usually higher than the reference range. In contrast, humoral factors are accompanied by evil
