| description | Flow cytometric immunophenotyping evaluation for presence or absence of the CD11/CD18 complex using monoclonal antibodies directed against the CD11 isoforms, CD11a and CD11b, and CD18 antigens. Defects in CD18 expression lead to either very low or no surface membrane expression of alpha chains CD11a, CD11b, and CD11c. Testing is performed for the diagnosis of leukocyte adhesion deficiency syndrome type 1 (LAD-1), an autosomal recessive disorder caused by mutations in the common chain (CD18) of the beta2-integrin family. | |
