title: [Application research of protein test by using biuret reagent].
abstract: OBJECTIVE
  To investigate the biuret reagent to detect proteins in the application, the impact of different test conditions for test results.
  
  
  METHODS
  The biuret method to select three different instruments, reagents, calibrators are arranged in combination to form 27 sets of detection systems, each detection system is a combination of 5 serum samples for testing, 5 measured values obtained, the selection process normality good a serum for the study to determine the mean value of all AST after culling outliers obtained in order to calculate the various detection systems use a combination of biuret reagent to detect proteins bias.
  
  
  RESULTS
  The use of different detection equipment to detect proteins biuret reagent bias, homogeneity of variance (P = 0.467), the difference was not statistically significant (F = 1.688, P = 0.421). different detection reagents using biuret reagent to detect proteins bias, homogeneity of variance (P = 0.574), a statistically significant difference (F = 5.784, P = 0.011). different calibrators use biuret reagent to detect proteins bias, homogeneity of variance (P = 0.467), the difference was statistically significant (F = 5.289, P = 0.000).
  
  
  CONCLUSIONS
  Biuret reagent in the detection of protein applications, impact detection reagents and calibrators will test result, during the test than when it is necessary to detect deviation detection reagents and calibrators due to be considered.
