[Materno-foetal transfer of anti-HLA antibodies. Study by using LDA test (author's transl)].

The LDA test was used to study the materno-foetal transfer of anti-HLA antibodies. The results were compared with those obtained earlier by the complement dependent lymphocytoxicity test (CdL). Although more sensitive than CdL, the LDA test did not demonstrate more maternal antibodies in cord blood when these antibodies corresponded to the child's paternal antigens. Nevertheless LDA demonstrated antibodies did not always behave similarly to those seen by CdL.
