title: [Some questions about blood group nomenclature].
abstract: Author in introductory part of the paper deals with several basic principles of the scientifical nomenclature, then with the up to date definition of "blood-groups". The so called "blood-groups" in the human and in animals represent biochemical, more exactly structurechemical polymorphisms, i.e. they are genetically regulated inherited variants of some functionally basic molecules. Consequently the expression "blood-groups"--which originally implied Landsteiner's ABO-system and it's groups--nowadays include various types (erythrocyte-membrane, serum, enzym etc.) of structural polymorphisms. Author recommends to sign serum samples ("Serotypes") as anti-A, anti-B and anti-A + B. Definition of "sub-groups" and "variants" is given. Author deals with the nomenclature of Rh-system including Rh-phenotypes and genotypes. At last description of symbols used in blood-group systems is given.
