目的加强献血者献血前ALT初筛,严把采血关,保证血液安全,防止血液资源浪费。方法应用威图M-300半自动血清生化分析仪对献血者献血前ALT快速检测,并根据季节温度的变化及血样标本复检ALT值升高情况,适宜调整ALT初筛值。结果2010年度应用威图M-300半自动血清生化分析仪,对献血者献血前进行ALT初步筛查,使ALT升高所引起血液报废率下降至2.7%。2011年度我们将献血者ALT初筛值下调(1～3)U/L,使ALT值升高导致血液报废率再度下降至1.1%。结论适宜调整献血前ALT初筛值,防止献血后由于血液标本保存时间、温度等原因导致单纯ALT偏高引起的血液报废,取得满意效果。
Objective To enhance the pre-screening of blood donors before blood donation ALT, strict blood sampling, to ensure blood safety and prevent the waste of blood resources. Methods Rituximab M-300 semi-automatic serum biochemical analyzer was used to detect the serum ALT level before blood donation. According to the change of seasonal temperature and blood sample, the initial ALT value was adjusted appropriately. Results In 2010, we applied the Rittal M-300 semi-automatic serum biochemical analyzer to conduct primary ALT screening before donating blood to blood donors, and the blood scrap rate dropped to 2.7% due to increased ALT. In FY2011, we reduced the primary screening level of ALT in blood donors (1-3) U / L, resulting in an increase in ALT resulting in an additional 1.1% reduction in blood reject rate. Conclusion It is appropriate to adjust the pre-serum ALT before blood donation to prevent the blood from being scrapped due to high ALT after blood donation due to the preservation time and temperature of blood samples, which achieves satisfactory results.
