Detection of Antileukocytic Antibodies in Blood Serum using Lymphocytes and Latex Microspheres Carrying HLA-Antigens upon Alloimmunization of Women with Recurrent Pregnancy Loss

Аннотация

Anti-HLA-antibodies were detected using cross-reaction of blood serum with allogenic T and B cells and latex microspheres coated with HLA-I and HLA-II antigens. HLA+ and HLA–sera obtained from women before and after allogeneic immunization were tested. The results obtained by these methods significantly differed. The test with latex microspheres detected antibodies to HLA-I and HLA-II antigens with high sensitivity and specificity and can be used for assessment of clinical significance of alloantibody detection when using alloimmunization in the therapy of gestation disorders.
