How a Urinalysis Is Done
In most cases, urine is collected in a clean container, then a plastic stick that has patches of chemicals on it (the dipstick) is placed in the urine. The patches change color to indicate things like the presence of glucose or white blood cells.
The doctor or laboratory technologist also usually examines the urine under a microscope to check for other substances that indicate different conditions.
If a urinalysis shows white blood cells and bacteria — which may mean that there's an infection in the kidneys or the bladder — the doctor may decide to send the urine to a lab for a urine culture to identify bacteria that may be causing the infection.
Getting a urine sample. It can be difficult to get urine samples from kids to analyze for a possible infection. That's because the skin around the urinary opening normally is home to some of the same bacteria that cause infections in the urinary tract. If these bacteria contaminate the urine, the doctors may not be able to use the sample to tell if there is an infection or not.
To avoid this, the skin surrounding the urinary opening has to be cleaned and rinsed immediately before the urine is collected. In this "clean-catch" method, the patient (or parent) cleans the skin around the urinary opening. The child then urinates, stops momentarily (if the child is old enough to cooperate), then urinates again into the collection container. Catching the urine in "midstream" is the goal.
