传统的血型鉴定实验方法是用A型和B型标准血清,实验时,需用生理盐水制备血悬液,由于用品较多,学生具体操作时较为忙乱,既费时,判定结果又容易出错(因A型和B型标准血清中分别含抗B和抗A凝集素).为克服上述缺点,可直接到医院购买抗A和抗B两种标准血清,省去制备血悬液这一步骤.具体做法是:实验前,将部分载玻片消毒.未消毒的一载玻片,置于实验台上,然后在该玻片的左、右两侧分别滴一滴抗A和抗B标准血清(注意两者不能混合).再取一消毒用酒精棉 The traditional blood type test method is the use of type A and type B standard serum, the experiment, the need for the preparation of blood suspension with saline, due to more supplies, students are more hectic concrete operation, both time-consuming, the results are easy to make mistakes (due to A and B standard serum containing anti-B and anti-A lectin, respectively.) To overcome the above shortcomings, you can go to the hospital to buy anti-A and anti-B two standard serum, eliminating the need for the preparation of blood suspension step. The practice is to sterilize part of the slide prior to the experiment, and a non-sterile slide is placed on a bench, and then a drop of anti-A and anti-B standard serum is applied to the left and right sides of the slide The two can not be mixed.) Then take a disinfection of alcohol cotton
