The calcium tolerance test is of diagnostic importance only in osteomalacia, which it helps to identify before bone biopsy when the static phosphocalcic parameters are not a deciding factor. However, the test does not make it possible to distinguish an osteoporosis from a cortisone osteopathy or an idiopathic hypercalciuria. In the first two diseases, the rates of urinary calcium elimination are comparable to that of normal individuals. It seems that the rate of urinary elimination of I.V. administered calcium is, approximately, all the more elevated as the level of iPTH is low; and, when the level of iPTH is low, the osteoid tissue seems less calcified than normally.
钙耐量试验仅在骨软化症中具有诊断意义，当静态磷钙参数不是决定因素时，它有助于在骨活检前识别骨软化症。然而，该试验无法区分骨质疏松症与皮质醇性骨病或特发性高钙尿症。在前两种疾病中，尿钙排泄率与正常个体相当。静脉注射钙的尿排泄率似乎大致是，甲状旁腺激素（iPTH）水平越低，排泄率越高；而且，当iPTH水平较低时，类骨质组织的钙化似乎比正常情况少。
