Laboratory of Tissue Immunology was founded in 1971 by prof. Henryk Matej who was the first in Poland to perform human leucocyte antigen (HLA) typing. In 1992-2014, the Laboratory was headed by dr Beata Nowakowska, who continued histocompatibility testing for recipients and donors of bone marrow and kidney transplantations. Prof. Katarzyna Bogunia-Kubik has been heading the Laboratory since 2014. Ever since 1977, the Laboratory has been working with Regional Transplantation Centres, dialysis stations, as well as with the State Organ Transplant Waiting List, as part of cooperation with Poltransplant. It also performs testing for the Limb Replantation, Microsurgery, and Hand Surgery Hospital Division in Trzebnica, as well as cross-matching for the Department of Thoracic Diseases in Szczecin (lung transplants) and Centre for Heart Diseases in Zabrze (heart transplants). Since 1990, the Laboratory has been commercially testing patients for genetic predisposition for autoimmune diseases (including: rheumatic diseases, uveitis, recurrent iritis, psoriatic arthritis, type 1 psoriasis, coeliac disease). Additionally, it has been typing HLA, KIR receptor, and anti-HLA antibody levels to assist in diagnosis of infertility and recurrent pregnancy loss. Since 2005, the Laboratory has been operating as part of the Medical Centre at HIIET PAS. It is registered in KIDL (registration number: 2454), and has received accreditation from the European Federation for Immunogenetics in 2018.
