Abstract:

Objective To prepare a liquid internal quality control material for homocysteine (Hcy) without assigned value,and to investigate its performance. Methods Pooled human serum was used as the medium of the quality control material for Hcy.The homogeneity and stability of quality control material were evaluated according to CNAS-GL03. The self-made quality control material was also used in internal quality control and was compared with RANDOX quality control material. Results The homogeneity and stability of the self-made quality control material met related requirements.Compared with RANDOX quality control material,there was no statistical significance (P>0.05). Conclusions The self-made quality control material for Hcy has good homogeneity and stability,and it can be used for the internal quality control in clinical laboratories.
