血型检查中,Ax亚型极为罕见,Salmon(1960)报道法国Ax亚型的出现率约为A型的1/40,000。在上海地区,据调查约为1/60,000。日本1978年报道只发现3个Ax亚型家系。最近,我们发现一女献血员周××,20岁,未婚,属于Ax亚型。特报告如下: 实验室检查及分析一、ABO血型检查:本例红细胞与抗A和抗B血清均未发生凝集,而其血清与A及B细胞又均有凝集发生(表1),因此,血型可判为O型。但本例红细胞与20份不同来源的O型人有血清呈现较好的凝集,说明本例又非O
Ax subtype is extremely rare in blood tests. Salmon (1960) reported that the incidence of Ax subtype in France is about 1 / 40,000 of type A. In the Shanghai area, it is estimated at about 1 / 60,000. Japan reported only three Ax subtype families in 1978. Recently, we found a female blood donor week × ×, 20 years old, unmarried, belong to the Ax subtype. Special report is as follows: Laboratory tests and analysis First, ABO blood group examination: This case of erythrocytes and anti-A and anti-B serum did not occur agglutination, and its serum and A and B cells have agglutination occurred (Table 1) Blood type can be judged as O-type. However, this example of red blood cells and 20 different sources of O-type human serum showed better agglutination, indicating that this case is not O
