Bacteriuria is a laboratory symptom that characterizes the presence of bacteria in the urine. Most often, this indicates a urinary tract infection (kidney, bladder), but may be a harmless laboratory finding. Clinical manifestations can be varied - from an absolutely asymptomatic course to pronounced signs (fever, back pain, urination disorders). The presence of bacterial flora in the urine is investigated in several ways - physicochemical, bacteriological, etc. Correction of bacteriuria is carried out by the appointment of antibacterial drugs.
Bilirubinuria is a pathological condition characterized by the presence of bilirubin in the urine. The causes are diseases of the liver and biliary tract (BI). A high concentration of bilirubin stains the urine dark brown. The test for bilirubinuria together with the test for urobilinogenuria (detection of bilirubin derivatives in the urine) is used for the differential diagnosis of jaundice - parenchymal, hemolytic, obstructive. Treatment of the underlying disease is necessary to correct bilirubinuria.
