INVESTIGATION ON RELATIONSHIP BETWEEN PREOPERATIONALSENSITIZATION AND CROSSMATCH

Objective To explore the relationship between HLA sensitization and crossmatch and to assess its clinical value. Methods The subjects were divided into 3 groups :high sensitization group (PRA≥40％),low sensitization group (40％＞PRA≥10％) and non-sensitization group (PRA＜10％) according to the HLA antibody level detected by ELISA. The results of crossmatch were compared among the 3 groups. Results There was significant difference among the ratio of positive crossmatch in high sensitization group (39.4％),low sensitization group (10.5％)and non-sensitization group (2. 6％). Conclusion The sensitization level is positively correlated with the result of crossmatch. The improvement of matching precision can be made by using both of techniques mentioned above.
