目的了解血小板捐献期限改为14 d后,长期捐献血小板的献血者血液常规的变化对血小板质量以及对献血者健康的影响。方法采用全血细胞自动计数仪检测献血者血液常规,显微镜下检测血小板中红细胞的含量,酶联免疫法检测献血者血清铁含量。结果产品质量能够达到国家标准,但一部分捐献者红细胞MCV、MCHC、MCH等检测项目低于正常值,血清铁含量低于正常值。结论血小板捐献期限改为14 d后,对血小板产品没有影响,但有影响献血者健康的潜在因素。
Objective To understand the effects of routine changes of platelet blood donors on platelet quality and blood donor health after platelet donation period was changed to 14 days. Methods Blood samples were collected from blood donors by automatic blood cell counter. The contents of erythrocytes in platelets were detected by microscopy. Serum iron levels were measured by enzyme - linked immunosorbent assay. Results The product quality can meet the national standard, but some donors such as MCV, MCHC, MCH and other test items are lower than the normal value, the serum iron content is lower than the normal value. Conclusion The change of platelet donation period to 14 days has no effect on platelet products, but there are potential factors that affect the health of blood donors.
