Abstract: Objective　To investigate the correlation between urine conductivity and urine freezing-point osmotic pressure determined by UF-1000i urine analyzer.  Methods　（1）The conductivity levels of urine samples of 1 064 healthy subjects were determined. The reference range of urine conductivity in healthy subjects was obtained.（2）A total of 137 random samples were determined for the urine conductivity by UF-1000i and classified into normal group and normal reference range exceeding group，and the urine freezing-point osmotic pressure was determined by Model 3300 Micro-Osmometer. The results of correlation were analyzed.  Results　（1）The reference range of urine conductivity was 5.56-30.29 ms/cm.（2）The conductivity of normal reference range group was correlated to the osmotic pressure（r＝0.942）. The linear regression equation of osmotic pressure against conductivity was Y＝34.18X－42.29. The conductivity of normal reference range exceeding group was correlated to the osmotic pressure（r＝0.979）.The linear regression equation of osmotic pressure against conductivity was Y＝32.34X＋4.12.  Conclusions　It is more convenient to determine the urine conductivity by UF-1000i together with routine urinary examination in daily work than testing the urine osmotic pressure，which is beneficial for estimating renal concentration and dilution function properly.
