title: [The clinical significance of detection of urinary ceruloplasmin in type 2 diabetes].
abstract: OBJECTIVE
  To evaluate the clinical significance of detection of urinary ceruloplasmin (Cp) in type 2 diabetes.
  
  
  METHODS
  To measure albumin/creatinine(Alb/Cr) and Cp/Cr in morning urinary specimens, from 134 normal controls and 3 960 diabetes, with RIA and ELISA separately.
  
  
  RESULTS
  (1) The range of urinary Cp/Cr for normal controls was 0.01 - 1.12 ng/mmol, median 0.36 ng/mmol. Cp/Cr > 0.924 ng/mmol was considered as abnormal, and there was no significant difference between males and females, as well as among subjects of different age. (2) The sensitivity and specificity of Cp/Cr were 90% and 66% respectively with Alb/Cr > 2.5 mg/mmol as a golden standard for diabetic nephropathy, and Kappa value 0.48. Urinary Cp/Cr correlated well with Alb/Cr. (3)After sub-maximal exercise, Cp/Cr elevated markedly with no significant change of Alb/Cr.
  
  
  CONCLUSIONS
  Urinary Cp/Cr could be considered as a marker of diabetic nephropathy and might be more sensitive than Alb/Cr.
