Richland College Biol. 2402 th Edition EXERCISE 41A – URINALYSIS OBJECTIVES To list the physical characteristics of normal urine—color, specific gravity, pH. To list substances found in normal urine and substances not normally found in urine. To describe common conditions associated with glycosurian, proteinuria, ketonuria, hematuria, high bilirubins in urine, casts, and white blood cells in urine. To run certain urinalysis tests, understand the purpose of each, the materials required, and a summary of the procedure. ACTIVITY 1: ANALYSIS OF URINARY COMPONENTS tests are run on unknown urine and students’ urine PHYSICAL CHARACTERISTICS: color, transparency, pH INORGANIC CONSTITUENTS: sulfates, phosphates, chlorides ORGANIC CONSTITUENTS: urea protein/albumin
