HI rubella antibody determination. (A comparison of methods proposed for the removal of non-specific inhibitors).

The Authors consider the different methods so far proposed for the selective removal of non-specific inhibitors for HI rubella antibodies. They show that the best results are obtained by dextran sulphate and acetone treatments, while the kaolin and heparin-MnCl2 procedures should be avoided especially in the serological diagnosis of acute rubella infection. The presence of specific IgM was demonstrated by 2-mercaptoaethanol.
