Abstract
Objective To study the causes of coagulation and hemolysis of blood samples collected from cardiovascular disease patients and the method to prevent its happening in order to reduce the numbers of coagulation and hemolysis samples.Methods All the blood samples of cardiovascular disease patients were randomly divided into control group( n =7396)and experimental group (n =7334 ).Control group was collected and transported according to the traditional methods,while the experimental group adopted standard control in sample collecting,transporting,laboratory transmission.Causes of the blood sample coagulation and hemolysis in two groups were observed.Results Unqualified blood samples ratio of experimental group was 0.21％significantly lower than 0.82％ that of the control group ( x2 =27.599,P ＜ 0.01 ).The ratio of coagulation and hemolysis of experimental group was 0.18％,and that of control group was 0.65％,and the difference was statistically significant (x2 =19.923,P ＜ 0.01).Conclusions Quality control of each procedure in the blood sample before examination can effectively reduce the number of unqualified blood coagulation and hemolysis and improve the quality of overall blood samples,and further provide reliable and accurate scientific evidence for disease diagnosis.
