[An analysis of the activities of the United Register of Typed Donors and of the status of tissue typing in different regions of Russia].

The paper presents a review of the activities of the National Register of Typed Donors in connection with 1.5-year activity of the World Donor of Bone Marrow Association. The search for donors was performed for all European and American countries using myelotransformation from unrelated donor. Basing on I class HLA-antigen phenotyping frequency, split typing and DR-antigens, conclusions are drawn as to the condition of tissue typing by the register as a whole and for separate regions of the country. The composition and contamination with nonmonospecific sera of the National Panel of Typing Sera have been reviewed in comparison with reference panel one lambda.
