Lr dose
Lr dose
,the limes reacting dose of diphtheria toxin, that is, the smallest amount of toxin that, when mixed with one unit of antitoxin and injected intracutaneously in the shaved skin of a susceptible guinea pig, yields a minimal, positive reaction and inflammation localized to the region of the injection; the Lrd. closely approximates the Lod., as would be expected, inasmuch as a slight excess of unneutralized toxin results in a reaction.
