血小板输注的主要问题在于容易产生血小板输注无效性。这通常由血液中HLA同种免疫引起。通过检测HLA抗体和临床血小板输注无效,可以评价是否发生同种免疫。本文作者于1988～1992年间对50例癌症患儿输注少白细胞的血液成分。患儿平均年龄6岁(1.3～17.8岁)。从未接受过非过滤血液输注。对照组由10位患儿(1～15岁)组成,每人至少曾接受过10次非过滤血液输注,在本次研究中 The main problem with platelet transfusions is the ineffectiveness of platelet transfusion. This is usually caused by HLA alloimmunization in the blood. By detecting HLA antibodies and clinical platelet transfusions invalid, you can assess whether allogeneic immunization occurs. The author in 1988 to 1992 in 50 cases of infants with leukemia transfusion of blood components. Children with an average age of 6 years (1.3 to 17.8 years old). Never received unfiltered blood transfusions. The control group consisted of 10 infants (aged 1 to 15 years) who had received at least 10 nonfiltered blood transfusions per person. In this study
