1.问:什么叫血型? 答:个体血液中红细胞、白细胞、血小板、血清蛋白的抗原的差异叫血型。 2.问:哪些血型与临床的关系最大? 答:红细胞的血型与临床关系最大。目前已知红细胞中有近二十个系统和高低频率两组约400种以上的抗原。其中以ABO系统的抗原为最重要;Rh系统的抗原次之。因ABO系统存在着天然抗体(表1),且这种抗体(也叫凝集素)在37℃下有免疫活性,所以,在临床输血时,一旦供血者与受血者的ABO血型不合,受血者体内的抗体就会与输入的相应抗原起作用而发生血管内溶血。Rh阳性的人虽然在人群中占99％左
1. Q: What is blood type? A: The individual blood red blood cells, white blood cells, platelets, serum protein antigen difference is called blood type. 2. Q: Which blood type has the highest correlation with clinical? A: The blood type of erythrocytes is the most clinically relevant. Nearly twenty systems are known to date in erythrocytes and about 400 or more in two groups of high and low frequency. Among them, the ABO system antigen is the most important; Rh system antigen second. Due to the existence of a natural antibody in the ABO system (Table 1) and the antibody (also called lectin) is immunologically active at 37 ° C, in the case of clinical transfusion, once the ABO blood group of the donor and the recipient are not matched Antibodies in the blood of the body will enter the corresponding antigen and the role of the occurrence of intravascular hemolysis. Although Rh positive people account for 99% of the population left
