The main tasks of LTK are:

• ensuring infectious and immunohematological safety of donor blood, its components and preparations.
• Conducting studies for antigen / antibodies to HIV 1, 2, antigen / antibodies to hepatitis C virus, HBsAg of hepatitis B virus, and total antibodies to Treponema pallidum (syphilis) by methods, ELISA, IHLA and PCR, and also complementary methods are used diagnostics, in accordance with regulatory documents and testing algorithms individually for each infection.
• testing of blood samples from donors, recipients, patients, pregnant women for blood groups according to the ABO system and Rh-affiliation in order to ensure the immunohematological safety of blood transfusion and the quality of blood and its components;
• Performing the full volume and proper quality control of laboratory tests to ensure the safety of blood transfusions.
• screening of anti-erythrocyte alloantibodies in the blood serum of donors, recipients, pregnant women;
• providing methodological assistance to the structural units of the RCC on laboratory examination of donors and medical organizations to ensure the immunohematological safety of blood transfusion therapy.
