糖化血红蛋白|被误解的糖化血红蛋白|全国检验与临床思维案例( 三 )


案例总结
由于HbTakasago 变异和患者HbA1C异常原因未得到充分认识 , 导致无法准确解释此异常结果的原因 。当工作中发现异常的HPLC色谱图时 , 检验人员有必要与临床医生沟通 。鉴于其遗传性 , 必须充分认识到有效筛查异常血红蛋白病对于提高人群质量的重要意义 。
专家点评
张玫四川大学华西医院实验医学科副主任技师
中国2型糖尿病防治指南(2020版)已将糖化血红蛋白作为糖尿病诊断标准之一 , 临床上应充分了解影响糖化血红蛋白的影响因素 。该病例报道了由于变异体导致HPLC法检测糖化血红蛋白异常增高的案例 , 难能可贵的是 , 作者发现了家系中也存在此变异体 , 提示患者家人也应注意此干扰的存在 。
