hay's test procedure, Principle, Uses, reagents Preparation and results Interpretation with normal reference range bile salts test. Hay's test, also known as Hay's sulphur flower test, is a chemical test used for detecting the presence of bile salts in urine. Sulphur powder is sprinkled into a test tube with three millilitres of urine and if the test is positive, the sulphur powder sinks to the bottom of the test tube. Sulphur powder sinks because bile salts reduce the surface tension of urine.
