[3-hydroxyanthranilic acid content in the urine of bladder cancer patients].

: The work has shown the possibility to determine immunologically 3-OAA-antigen in the urine of bladder cancer patients, which is absent in the urine of healthy individuals. By the identity reaction the authors proved the supposed structure of the detected antigen, i. e. the presence of 3-oxianthranilic acid in it. The data obtained may lie in the basis of the immunodiagnostic test to bladder cancer.
