TEST FOR DETECTION OF BILE SALTS IN URINE

Bile salts are salts of four different types of bile acids: cholic, deoxycholic, chenodeoxycholic, and lithocholic. These bile acids combine with glycine or taurine to form complex salts or acids. Bile salts enter the small intestine through the bile and act as detergents to emulsify fat and reduce the surface…

TEST FOR DETECTION OF BILIRUBIN IN URINE

Bilirubin is converted to non-reactive biliverdin on exposure to light (daylight or fluorescent light) and on standing at room temperature. Biliverdin cannot be detected by tests that detect bilirubin. Therefore fresh sample that is kept protected from light is required. Findings associated with bilirubinuria are listed below. Jaundice Urine color:…

TESTS FOR DETECTION OF KETONES IN URINE

The proportion of ketone bodies in urine in ketosis is variable: β-hydroxybutyric acid 78%, acetoacetic acid 20%, and acetone 2%. No method for detection of ketonuria reacts with all the three ketone bodies. Rothera’s nitroprusside method and methods based on it detect acetoacetic acid and acetone (the test is 10-20…

TESTS FOR DETECTION OF GLUCOSE IN URINE

1. COPPER REDUCTION METHODS A. Benedict’s qualitative test: When urine is boiled in Benedict’s qualitative solution, blue alkaline copper sulphate is reduced to red-brown cuprous oxide if a reducing agent is present (Figure 820.1). The extent of reduction depends on the concentration of the reducing substance. This test, however, is…
