Check for possible Urinary Tract Infection through Leukocytes and Nitrite Test. Leukocytes indicate white blood cells in the urine, while Nitrite screens possible asymptomatic infections caused by nitrate-reducing bacteria. A positive Leukocytes and Nitrite test suggests a possible UTI. The Urobilinogen and Bilirubin tests are most commonly used to screen liver diseases. The presence of excreted Urobilinogen and Bilirubin suggests a possible deterioration of liver functions and an early indication of possible liver disease. Ideal result for Urobilinogen is less than 17 mol/l (< 1mg/dl) and Bilirubin should be negative. A positive protein test in urine usually indicates Proteinuria, the presence of protein in the kidneys. The pH test measures the acidity of urine. A result of approximately 7.0 indicates a balanced body pH.
