[Preliminary studies on the immune response to tetanus antitoxin: use of dried blood on filter paper]. / Etude préliminaire de la réponse immunitaire au vaccin antitétanique : utilisation desang séché sur papier filtre.

The tetanus antitoxin titers of blood obtained by venepuncture and those of finger-blood absorbed on filter paper are compared when the titration techniques use fresh or formalinized erythrocytes sensitized by the bis-diazotized benzidine (BDB) method. The results show that the antitoxin titers are closely similar with the two methods of sampling and storage.
