Abstract:
The aim of this study was to find an effective solution for difficulty of blood matching. Twenty nine cases with clinical difficult in blood matching were collected, classified by their etiological factors, and analyzed with all the antibodies in serum. RBC from health donor were incubated with mPEG-BTC at 25 degrees C for 1 hour. The coagulation of patient serum and donor RBC before and after mPEG-BTC camouflage was detected and compared by polybrene and antihuman globulin reagents. The result showed that 29 cases with difficult blood matching mainly suffered form blood diseases and tumors. The main antibody were Rh and autoantibody. Donor RBC modified by mPEG showed no coagulation with the blood serum in the patients with problems of blood matching. In conclusion, the modification of RBC with mPEG-BTC provides a useful strategy for resolving problem of clinical difficulty in blood matching.
