Application analysis of venous blood and peripheral blood in blood routine test
Objective To explore the application value of venous blood test and peripheral blood test in blood routine test,in order to provide reference for improving the accuracy of clinical blood routine test.Methods A total of 150 suspected cases of lesions were selected for blood routine testing at Nanping City Jianyang District Tongyou Street Community Health Service Center from April 2021 to April 2022,and both venous and peripheral blood tests were used.The confirmed result of retesting was the gold standard,the diagnostic results,diagnostic efficacy,blood indicators and satisfaction rate of tested subjects of two testing methods were recorded.Results According to the gold standard test,102 cases were positive and 48 cases were negative.The sensitivity,specificity and accuracy of venous blood test were 96.08％,93.75％and 95.33％,respectively,which were higher than those of peripheral blood test with 85.29％,75.00％and 82.00％,respectively,and the differences were statistically significant(x2=7.022,6.400,13.268,P＜0.05).The levels of hemoglobin,red blood cells and white blood cells in venous blood test were lower than those in peripheral blood test,and the levels of platelets was higher than that in peripheral blood test,and the differences were statistically significant(P＜0.05).The total satisfaction rate of venous blood test for the tested subjects was 98.67％,which was higher than the 93.33％of peripheral blood test,and the difference was statistically significant(x2=5.556,P＜0.05).Conclusion The diagnostic efficacy of venous blood test in routine blood tests was more ideal than that of peripheral blood test,the error of various blood indicators obtained from the test was smaller,and it was less susceptible to external interference,the test results were more accurate and it was worthy of clinical promotion and application.
