Inverse association between IgG–anti-κ autoantibody and CA in patients with cold agglutination. In a group of 302 patients, the titers of IgG–anti-κ and CA were determined (left and right ordinate). Sera with identical CA titers were included into the same group (abscissa). Anti-κ titers are given in OD 405 nm (median ± MAD).
