| Abstract: | Analysis of the saliva for evaluation of AB0 production should be carried out along with other studies in expert evaluation of disputable paternity and maternity and in cases with replacement of children. A total of 249 subjects (79 families) were examined. Salivary specimens from 72 families were analyzed; salivary specimens were not analyzed in 7 families in which both men and women had blood group IV (AB0) and no agglutinins were present in the serum. The production of isoantibodies alpha and beta is inherited similarly as the production of AB0 isoantigens. The majority (81.6%) of children whose parents were isoantibody producers, were isoantibody producers too. If one parent produced isoantibodies and the other not, the children were more often (68.1%) producers, but less often than in the previous category. If both parents were non-producers, the children were non-producers as well. |
