A modified haemagglutination inhibition test for rubella antibodies, using standardized freeze-dried reagents, was developed and compared with haemagglutination inhibition tests using fresh erythrocytes. This comparison was made in collaboration with six European laboratories. A total of 4205 serum samples were tested. The results show that:
(1) Sensitivity and reliability of the modified test are good;
(2) the modified test can be performed in glass tubes as well as in polystyrene microtitration plates.
