The kidneys remove waste material, fluids, and other substances from the blood. The urine can contain many different clues to how your body is doing. Your urine tells a lot about your health. The most common use of urinalysis is to detect substances or cells in the urine that point to different disorders.
Urinalysis is used to diagnose disease or to screen for health problems. In some cases, kidney disease might be suspected based on what is found.
In other cases, nothing important is found. The results of urine tests can be affected by diet, dehydration, medicines, exercise, and other factors. Sometimes, you will be asked to come back and give another sample. Many people are familiar with pregnancy tests that use urine to detect a substance that only pregnant women produce. Others are familiar with tests of the urine for employment or to test athletes, for example, to exclude drug use. But there are many other uses in medicine.

Urine can be tested for many different things. You might collect a urine sample at home or at your health care provider's office.
Providers typically give out containers for urine samples. You might be asked to collect the sample at home first thing in the morning, when your urine is more concentrated. You might be instructed to collect the sample midstream, using a clean-catch method. This method involves the following steps:.
In some cases, if needed, your provider can insert a thin, flexible tube catheter through the urinary tract opening and into the bladder to collect the urine sample. The urine sample is sent to a lab for analysis. You can return to your usual activities immediately. For a urinalysis, your urine sample is evaluated in three ways: visual exam, dipstick test and microscopic exam. A lab technician examines the urine's appearance. Urine is typically clear. Cloudiness or an unusual odor can indicate a problem, such as an infection.
Protein in urine can make it appear foamy. Blood in the urine can make it look red or brown. Urine color can be influenced by what you've just eaten or by certain drugs you're taking.
For example, beets or rhubarb might tint your urine red. A dipstick — a thin, plastic stick with strips of chemicals on it — is placed in the urine. The chemical strips change color if certain substances are present or if their levels are above typical levels.
