Summary

Blood stains belonging to various sub-group A combinations were examined by the absorption-elution method (in comparison with Holzer method and mixed agglutination). No difficulties were encountered in the identification of A1, A2, and A1B blood stains, while identification of A antigen in A2B stains was dubious (always negative with the others methods). This seemed to be due to low anti-sera titer in relation to A antigen in this subgroup combination.

Zusammenfassung

Mit Hilfe der Absorptions-Elutionsmethode wurden Blutspuren der verschiedenen A-Untergruppenkombination untersucht. Keine Schwierigkeiten traten bei Blutspuren, die A1, A2 und A1B enthielten, auf. Dagegen stieß man auf Schwierigkeiten bei der A-Antigenidentifikation in A2B-Blutspuren. Wahrscheinlich ist dies auf den niedrigen Titer der Antisera dem A-Antigen dieser Untergruppenkombination gegenüber zurückzuführen.
