Experiment confirms that the MRC grey wedge photometer is better for haemoglobinometry than the Sahli haemoglobinometer. However, there is considerable observer variation and the precision of those who undertake haemoglobinometry should be studied by analysis of duplicates. Only in this way can the significance of any measurements obtained be assessed.
实验证实,与萨利血红蛋白计相比,医学研究委员会(MRC)灰色楔形光度计更适用于血红蛋白测定。然而,观察者之间存在相当大的差异,进行血红蛋白测定的人员的精密度应通过双份样本分析来研究。只有这样才能评估所获得的任何测量结果的意义。
