[Cryopreservation of erythrocytes for performing serological reactions].

The possibility of using monkey red blood cells conserved by freezing at --196 degrees C in serological tests was studied. Hemagglutination and hemagglutination-inhibition tests with measles antigen and measles gamma globulin revealed no differences in the sensitivity of native and conserved red blood cells. The method of washing red blood cells from cryoprotective solution modified by the authors is described.
