Abstract: Objective: To compare the routine blood tests of venous blood and peripheral blood and analyze their clinical application value. Methods: Eighty patients with routine blood test collected in our hospital from February 2020 to October 2020 were selected and divided into two groups, control group and observation group, with 40 patients in each group. In the control group, peripheral blood was collected for routine blood test, while in the observation group, venous blood was collected for routine blood test, and the routine blood test of patients in the two groups was observed and compared. Results: The WBC in the observation group was significantly higher than that in the control group, and the difference was statistically significant.Compared with the control group, platelet (PLT), mean red blood cell hemoglobin content (MCHC), mean red blood cell volume (MCV), hemoglobin (Hb), red blood cell (RBC), specific volume of red blood cell (HCT) and other related indicators were all higher than the control group (P<0.05). However, there was no statistically significant difference in MCH between the two groups(P>0.05).Blood routine test results showed that there was no statistical significance in RBC, WBC, MXD, PLT and other indicators detected within 3 h after venous blood collection compared with immediate test (P>0.05). There was no statistically significant difference in RBC and WBC (P>0.05),but MXD was significantly increased and PLT was significantly decreased (P<0.05). Conclusion: In routine blood test, the effect of venous blood test is more stable, but the time of sending blood test should be strictly controlled.
