Abstract
A method of indicating rheumatoid factors, primarily such rheumatoid factors which belong to immunoglobulin classes other than the immunoglobulin class IgM, in an aqueous sample. The sample is reacted in the presence of the complement factor C1q in non-bound form with soluble, aggregated immunoglobulin labelled with one or more analytically indicatable atoms or groups to selectively precipitate such rheumatoid factors which, in the presence of C1q, are able to precipitate aggregated immunoglobulin, whereafter the analytically indicatable atoms or groups are indicated in the precipitation phase and/or in the solution.
