Zusammenfassung:PROBLEM TO BE SOLVED: To simply detect the rejection reaction after organ transplantation by detecting the matrix metalloprotease 2 or its precursor in the body fluid to early detect the chronic rejection reaction after transplantation of an organ such as kidney. SOLUTION: The concentration of matrix metalloprotease(MMP)-2 or its precursor in human body fluid, for example, human urea or blood, is determined by the enzyme immunoassay, in addition the creatinine concentration is determined to correct the MMP-2 value with the creatinine concentration to give an index. The cut-off value for judging whether chronic renal transplantation rejection reaction has occurred or not is set between 0.0-20.0μg/g. creatinine and the cut-off value is set to 0.5-10.0μg/g. creatinine whereby the early detection of chronic post-operative rejection reaction becomes possible.
