DefinitionThis section has been translated automatically.
Intracutaneous test with erythrogenic streptococcus toxin for the detection of antibodies against erythrogenic toxins. 0.1 ml thick toxin is injected intracutaneously. Positive reaction: After 10-20 hours a redness of > 10 mm develops. If antibodies against erythrogenic toxins are present, the skin does not redden, the Dick-Test is negative. In the absence of antibodies, local exanthema is formed, the Dick test is positive and the patient is not immune to scarlet fever.
