Abstract: ObjectiveTo explore the abnormal detection rates in sceening of chronic kidney disease (CKD) in migrant children in Lanzhou Xigu district and to analyze the reason. MethodsA total of 1 233 migrant children ranging 68 years old were collected and  another 1 129 resident children were collected as control group. Urine test was performed in all children by urine test paper method. Among 2 332 children， repeat urine test was done in 147 children who had abnormal result in the first test. Children with abnormal urine result were divided into three groups: hematuria， proteinuria， hematuria and proteinuria， and bacteriuria. ResultsOur data showed that total detection rate was 13.6%， including hematuria 9.3%，proteinuria  0.4%，hematuria and proteinuria 0.3% and  bacteriuria  4.1%. The detection rate of hematuria (10.8%) in migrant childrenwas significantly higher than that of the resident children， but in proteinuria， bacteriuria， hematuria and proteinuria， there were no significant difference between them. The  detection rates of hematuria， hematuria and proteinuria and proteinuria were significantly higher in the male migrant children than in the male resident children. There were no significant difference in hematuria， proteinuria， hematuria and proteinuria， and bacteriuria between female migrant children and female resident children. In 147 cases of followup， 21 cases with simple hematuria were found， one case with henochschonlein purpura nephritis was found， two cases with urinary tract infection were found. ConclusionUrine screening is a convenient way for early detection of renal disorders in children. More attention should be paid to the positive screening results in the migrant children.
