A urinalysis is a test of your urine. It is often done to check for urinary tract infections, kidney problems, or diabetes. You may also have one during a checkup if you are admitted to the hospital, before you have surgery, or if you are pregnant. It can also monitor some medical conditions and treatments.
A urinalysis involves checking the urine for:
Its color
Its appearance (whether it is clear or cloudy)
Any odor
The pH level (acidity)
Whether there are substances that are not normally in urine, such as blood, too much protein, glucose, ketones, and bilirubin
Whether there are cells, crystals, and casts (tube-shaped proteins)
Whether it contains bacteria or other germs
