Overview:
The HA epitope tag (YPYDVPDYA) consists of 9 amino acid residues and comes from the Human influenza virus hemagglutinin [1].Hemagglutinin is a viral cell surface glycoprotein responsible for the binding of viral particles to their target cell, and is named because of its ability to agglutinate erythrocytes in vitro [2].

抗人球蛋白试验,又称Coombs’试验,是诊断自身免疫性溶血性贫血(AIHA)的重要依据。
正常人直接与间接试验均为阴性,Coombs’试验阴性有时并不能排除AIHA
