Human Urogenital System Health Investigation Purpose: In this investigation you will perform three classic urinalysis tests to investigate the urogenital health of four individuals. Objectives: 1) You will understand the basis of urinalysis and its application to the diagnosis of medical disorders. 2) You will diagnose several different medical disorders using simulated urine samples. 3) You will hypothesize (come up with an explanation based on your observations) as to what might be wrong (or not wrong) with each individual. Many diseases are identified and diagnosed based on recognizable signs and abnormalities called symptoms . Laboratory tests, such as X-rays and blood tests, help a physician make a correct diagnosis and also rule out any other disorders that may have some of the same symptoms. Many different tissues and fluids from the body-including blood, feces, and cerebrospinal fluids- are tested for symptoms of disease. Urine is just one of many body fluids that give a physician clues about a disease. Urine testing, or urinalysis, is a very important diagnostic tool. It involves the physical, chemical, and visual examination of a patient’s urine sample. A thorough analysis of the urine may provide more information about the general condition of the body than any other set of tests. Urinary tract infections, kidney malfunction, diabetes, and liver disease are just some of the medical problems that can be diagnosed through urinalysis. Several factors are examined when analyzing a urine sample: color and appearance, pH, microscopic appearance, and presence of glucose and proteins. The color of normal urine ranges from pale yellow to amber, depending on the concentration of the pigment urochrome, which is the end product of the breakdown of the blood protein hemoglobin. The appearance of the urine may serve as an indication of a disorder. Pale yellow urine, for example, may indicate diabetes insipidus or granular kidney , or the urine may simply be very dilute due to the ingestion of large amounts of water. A milky color might signify
