Quality analysis of blood cell testing in clinical medical testing
Objective To investigate the results of blood cell testing during clinical medical testing and explore methods to ensure the quality of testing.Methods 60 patients who underwent blood cell tests were selected as the survey subjects.The test results under different storage time and anticoagulant ratios were retrospectively analyzed,and the occurrence of hemolysis events under different storage time were statistically analyzed.Results Hemoglobin,platelet count,white blood cell count and red blood cell count at an anticoagulant ratio of 1∶1000 were(144.31±10.69)g/L,(184.49±24.94)×109/L,(10.33±1.89)×109/L,and(5.41±0.91)×1012/L,which were higher than(106.22±7.09)g/L,(134.01±20.69)×109/L,(6.31±1.01)×109/L,and(3.92±0.61)×1012/L at an anticoagulant ratio of 1∶5000(P<0.05).The hemoglobin,platelet count,white blood cell count and red blood cell count with a storage time of 2 and 4 h were higher than those with a storage time of 0.5 h(P<0.05).The hemoglobin,platelet count,and white blood cell count with a storage time of 4 h were higher than those with a storage time of 2 h(P<0.05).Hemolysis events occurred after storage for 0.5,2 and 4 h,with 1,3 and 7 cases,accounting for 1.67%,5.00%and 11.67%,respectively.The incidence of hemolysis events after storage for 4 h was higher than that after storage for 0.5 h(χ2=4.821,P=0.028<0.05).Conclusion Anticoagulant ratio and the storage time of blood specimens can both affect the results of blood cell tests,and long-term storage of specimens can also lead to hemolysis events.During the process of blood cell testing,it is necessary to strictly control the proportion and storage time of anticoagulants,strengthen the control of each step,and improve the accuracy of the test results.
