Methods: In this study, 30 patients who visited the hospital in October 2023 were randomly selected and divided into two groups (15 cases in each group). The same collection method was used for routine blood tests. The tests were performed after anticoagulation and standing for 5 minutes, 1 hour, and 5 minutes, 2 hours respectively, and the routine blood test indicators at different time points were compared. Results: After comparison, there were no significant differences in the results of routine blood tests at 5 minutes after mixing, anticoagulating, and standing peripheral blood and those at 1 hour and 2 hours (P > 0.05). Conclusion: The results of peripheral blood after mixing, anticoagulating, and standing for 5 minutes are stable compared with those after standing for 1 hour and 2 hours. In actual work, the pre-test turnaround time can be appropriately extended.
