title: Comparison of architect I 2000 for determination of cyclosporine with axsym.
abstract: BACKGROUND
  Cyclosporine has been shown effective drug in suppressing acute rejection in recipients of allograft organ transplants.
  
  
  METHODS
  The cyclosporine concentration of 96 blood samples was determined using CMIA (chemiluminesecent microparticle immnoassay) Architect i 2000 and FPIA (fluorescence polarization immunoassay) AxSYM Abbott diagnostic. All patients have transplantation of kidneys and were hospitalized at Department of Nephrology at the Clinical center of University of Sarajevo. The reference serum range of cyclosporine for kidney organ transplantation for maintenance lies between 50 and 150 ng/mL. The quality control, precision and accurancy of Architect i 2000 were assessed.
  
  
  RESULTS
  The quality control was done using quality control serums for low (= 91 ng/mL), medium (= 328 ng/mL) and high (= 829 ng/mL). We have used commercial BIORAD controls and got reproducibility CV 5.83 % to 13 % for Architect i 2000. It was established that the main difference between Architect i 2000 and AxSYM and it was statistically significant for P < 0.05 according to Student t-test. Correlation coefficient was r = 0.903.
  
  
  CONCLUSIONS
  The CMIA Architect assay has significant reduced cyclosporine metabolite interference relative to other immunoassay and is a convenient and sensitive automated method to measure cyclosporine in whole blood.
