对青岛市区１４１０名２～１３岁健康儿童随意早餐后２～３ｈ尿标本的尿钙／肌酐比值（Ｃａ／Ｃｒ）进行检测，检测结果呈偏态分布，无年龄和性别差异，中位数为０．０９５，第９５百分位值０．２２．当尿Ｃａ／Ｃｒ比值＜０．２２时对高钙尿症筛查无假阴性，≥０．２２时应常规检测２４ｈ尿钙排泄量以确诊或排除高钙尿症。结果提示，随意早餐后尿Ｃａ／Ｃｒ比值可做为高钙尿症的初筛试验。
The urine calcium / creatinine ratio (Ca / Cr) in 1410 urine samples from 2 to 13 hours after breakfast in healthy children aged from 2 to 13 years in Qingdao City were detected. The results showed a skewed distribution without any difference in age and gender. The median Is 0.095, the 95th percentile value is 0.22. When urinary Ca / Cr ratio <0.22, no false negative for hypercalciuria screening, ≥ 0.22 should be routinely detected 24h urinary calcium excretion to confirm or rule out hypercalciuria. The results suggest that after random breakfast urine urinary Ca / Cr ratio can be used as a screening test for hypercalciuria.
