International standard for anti-canine-hepatitis serum.
The Central Veterinary Laboratory, Weybridge, England, was requested by the WHO Expert Committee on Biological Standardization to obtain suitable material for an international standard for anti-canine-hepatitis serum and to arrange a collaborative assay. Eight laboratories in 7 countries assayed a batch of anti-canine-hepatitis serum against 3 test preparations. On the basis of the results obtained, the material has been established as the International Standard for Anti-Canine-Hepatitis Serum and the International Unit of Anti-Canine-Hepatitis Serum has been defined as the activity contained in 0.0796 mg of the International Standard.
