Abstract:

Objective To investigate the reference method for hemoglobin(Hb)determination,and to provide a reference for trueness verification of Hb determination. Methods According to the requirements of the International Council for Standardization in Haematology(ICSH),UV-2550 spectrophotometer was used for Hb reference materials with low,medium and high levels being labeled by Japanese Reference Material Institute for Clinical Chemistry Standards and 2 trueness verification samples in the first External Quality Assessment of Shanghai Clinical Laboratory 2016. The precision,accuracy and comparability were analyzed. Results The total precision(CV)of the 5 samples using the reference method for Hb determination was <0.5%. The accuracy of Hb reference materials with 3 levels met the certification of reference materials. The bias of Hb determination total means (x?) determined by 615 clinical laboratories and Hb determination values by hematological analyzers with different brands was <2.7%,compared to reference method assignments. Conclusions The precision and accuracy of reference method for Hb determination by UV-2550 spectrophotometer meet related requirements. The level of Hb can be delivered well to routine hematological analyzers.
