title: Tn-polyagglutinability of red blood cells and acquired A-like specificity.
abstract: A woman whose red blood cells are polyagglutinable due to Tn-activation is reported. The true blood group of the patient is B but her cells have an acquired A-like specificity. The importance of the lectins, especially of Salvia sclarae extract, for the identification of Tn-polyagglutinability is demonstrated. The possibilities of A-like specificity of Tn-activated group B red blood cells is discussed.
