The 61D3 antibody is specific for human CD14, a 53-55 kDa GPI-anchored glycoprotein. CD14 is highly expressed on monocytes and to a lesser extent on interfollicular macrophages, and some dendritic cells. Together with LPS-Binding Protein (LBP), CD14 binds to and mediates the innate immune response to bacterial lipopolysaccharide (LPS).

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
