In Belgium 6000 non-remunerated donors regularly give plasma by the double plasmapheresis technique. The donation frequency is once every two weeks. Thus 75 000-80 000 liters of plasma are collected annually. This figure represents 7 500-8 000 liters of plasmapheresis plasma/10(6) inhabitants. Furthermore 5000 liters of plasma/10(6) inhabitants are recovered from whole blood (60% utilization of erythrocytes-concentrates). The 13 000 liters of plasma/10(6) inhabitants allow the country to cover all the national needs of albumin, coagulation factors and immunoglobulins. The programme is fully described and presented as a unique model of national self-sufficiency avoiding red cells wastage, and being entirely based on non-remunerated donors.
在比利时，6000名无偿献血者定期通过双重血浆置换技术捐献血浆。捐献频率为每两周一次。因此，每年收集75000 - 80000升血浆。这一数字相当于每10^6居民有7500 - 8000升血浆置换血浆。此外，每10^6居民还能从全血中回收5000升血浆（红细胞浓缩物利用率为60%）。每10^6居民13000升血浆使该国能够满足白蛋白、凝血因子和免疫球蛋白的所有国内需求。该方案有完整描述，并作为国家自给自足的独特模式呈现，避免了红细胞浪费，且完全基于无偿献血者。
