Method: from January 2019 to December 2020, Taiyuan Blood Center laboratory of 2 cases of 236628 blood type samples selected 1200 cases of unpaid blood donation samples as research samples, according to the random number method are divided into group A and B, group A routine screening blood test, group B in group plus alanine aminotransferase (ALT) early screening test. Comparative analysis of the test results between the two groups. Results: the scrap rate of group A blood samples was 0.33% higher than 1.67% in Group B (P <0.05);No laboratory review results and ALT (P> 0.05). Conclusion: the application of alanine aminotransferase (ALT) primary screening test in the blood test has high feasibility and has a significant role in reducing the blood scrap rate, which is worth recommended.展开更多
