A urinalysis is a test of your urine. A urinalysis is used to detect and manage a wide range of disorders, such as urinary tract infections, kidney disease and diabetes. A urinalysis involves checking the appearance, concentration and content of urine. Abnormal urinalysis results may point to a disease or illness.
Many types of test are used in analyzing the urine in order to determine whether it contains abnormal substances indicative of disease. The most significant substances normally absent from urine and detected by urinalysis are protein, glucose, acetone, blood, pus, and casts.
