Abstract

A method for immunological assay of IgM antibodies against at least one said antigen in a liquid sample containing at least IgM and IgG antibodies, such as a biological fluid, comprising reaction of said liquid sample and of antibodies against IgG, and addition to the so obtained reaction product of the said antigen bound to finely divided particles and of a free said antigen, the amount of IgM being inversely proportional to the amount of unagglutinated finely divided particles.
