[Staphylococcal coagglutination test for detecting antibody-coated bacteria in the urine].

: An easy and rapid staphylococcal coagulation test is described for detection of bacteria, covered with antibodies in urine of patients with chronic pyelonephritis as an additional index of the etiological role of the isolated microorganisms and localization of the pathological process. Inactivated and stabilized protein A containing strain S. aureus Cowan's (SSM 2352) was used. The coagulation test is negative in infectious processes of the lower segments of urinary system and bacterial contamination of urine.
