Abstract：Objective：To analyze the quality-influencing factors throughout the whole process of blood specimen testing，construct closed-loop whole-process quality control and prevention-control strategies，verify their clinical application effects，and improve the quality of blood specimen testing and the safety of clinical diagnosis and treatment. Methods：A total of 400 clinical blood specimens collected in our hospital from June 2025 to March 2026 were selected as research subjects. They were divided into the control group and the observation group according to whether the quality-control strategies were implemented，with 200 specimens in each group. The control group adopted the conventional specimen management mode，while the observation group received standardized quality-control interventions covering the whole procedures of specimen collection，transportation，storage，and detection. The unqualified specimen rates of the two groups were compared. Meanwhile，the professional competence and quality-control cognition level of 32 medical staff in relevant positions were compared before and after intervention. Results：After intervention，the total unqualified specimen rate of the observation group was 2.50%，which was significantly lower than 11.00% of the control group，with a statistically significant difference（χ2=11.534，*P*<0.01）. After intervention，the scores and total scores of medical staff in mastering standard operations，risk identification ability，quality-control cognition，and familiarity with regulations were significantly higher than those before intervention（*P*<0.001）. Conclusion：Unqualified blood specimens result from non-standard operations in multiple links of the whole testing process. The implementation of closed-loop whole-process quality control and prevention-controlstrategies can markedly reduce the unqualified specimen rate，effectively improve medical staff’s quality-control capability and professional literacy，and ensure accurate and reliable blood test results. which is suitable for clinical promotion and application.
