Criteria
For a disease to be regarded as an autoimmune disease it needs to answer to Witebsky's postulates (first formulated by Ernst Witebsky and colleagues in 1957 and modified in 1994):
- Direct evidence from transfer of pathogenic antibody or pathogenic T cells
- Indirect evidence based on reproduction of the autoimmune disease in experimental animals
- Circumstantial evidence from clinical clues

Famous quotes containing the word criteria:
“There are ... two minimum conditions necessary and sufficient for the existence of a legal system. On the one hand those rules of behavior which are valid according to the system’s ultimate criteria of validity must be generally obeyed, and on the other hand, its rules of recognition specifying the criteria of legal validity and its rules of change and adjudication must be effectively accepted as common public standards of official behavior by its officials.”
—H.L.A. (Herbert Lionel Adolphus)
“Every sign is subject to the criteria of ideological evaluation.... The domain of ideology coincides with the domain of signs. They equate with one another. Wherever a sign is present, ideology is present, too. Everything ideological possesses semiotic value.”
—V.N. (Valintin Nikolaevic)
“We should have learnt by now that laws and court decisions can only point the way. They can establish criteria of right and wrong. And they can provide a basis for rooting out the evils of bigotry and racism. But they cannot wipe away centuries of oppression and injustice—however much we might desire it.”
—Hubert H. Humphrey (1911–1978)
