[Recording the results of the indirect hemagglutination reaction in the microanalysis class by using vertical photometry].

A two-channel photometer is experimentally found to be suitable for vertical photometry to record the output of indirect hemagglutination, which is detected by the type of precipitates deposited on a parabolic bottom of sockets in microtitrimetric plane tables. Dynamic processes of depositing are studied as a function of sample volume and concentration of erythrocytic diagnosticum.
