Objective To Analyze the causes of abnormal color of plasma,so as to reduce waste of blood and ensure transfusion safety. Method Blood donors information was analyzed and the total bilirubin content of the plasma with abnormal color was detected from 2011 to 2014. Results The total bilirubin of the green anomaly plasma was found to be lower than that of normal plasma. Most plasma abnormalities were temporary,which was frequently seen in the fall and winter seasons.Repeatedly noted plasma color abnormalities accounted for 5.77%. Conclusion Edible pigment is most likely the reason in most of the green plasma. Some repeated abnormalities may be associated with liver metabolism and should not be used in blood donation.%目的 分析血浆颜色异常的原因,以采取有效措施,减少血液浪费,保证输血安全.方法 统计2011 ~ 2014年因血浆颜色异常的报废情况,分析颜色异常血浆的献血者情况和检测颜色异常血浆的胆红素含量.结果 绿色异常血浆的胆红素比正常血浆要低,其女性占多数,大多数血浆异常是暂时的,且多在秋冬季节出现,血浆颜色反复异常的占5.77%.结论 绝大多数绿色血浆是暂时性,可能与食用色素有关;少数反复异常可能与肝胆代谢有关,需要标注献血者信息,暂停其献血.
