[Different antibody tests (IgG, IgM) from children with chronical recurrent urinary tract infections (author's tranls)].

Different Antibody tests (IgG, IgM) were made from children with chronical and recurrent urinary tract infections with help of the indirect fluorescent method and were compared with the indirect hemagglutination test. The indirect hemagglutination gave absolutely higher antibody rest results, but the specifity of the immune fluorescence test is just as large. You can see the acute attacks of pyelonephritis in either the antibody response test or IHA test. It is quite important, in the beginning, to repeat the controlls of the antibody test, because the changes that could occure in the titer should be seen. The IgG antibody reactions rise slightly during the acute attacks of E. coli- and Enterococci reinfections.
