Sera of patients with pulmonary and extrapulmonary tuberculosis, of blood donors and cattle sera were researched in hemagglutination reaction, using untreated and papain-treated sheep erythrocytes, and in hemolysis reaction. 58% of patients with pulmonary tuberculosis and 23% of normal sera, reacted positive in at least one of the 3 reactions. 24 sera of 44 patients with extrapulmonary tuberculosis were found to be positive. The titer is important for diagnosis. In normal sera the highest titers were 1:64 in all reactions. Titers of 1:128 are to be considered as proof of tuberculosis. Considering the height of titers the hemagglutination-hemolysis reaction can also be used for diagnosis of tuberculosis in cattle.
