The kidneys are a pair of identical organs located inside the body near the middle of the back. In adults, each kidney is about the size of a fist. Shaped like the beans that carry their name, the kidneys filter waste out of the bloodstream, creating urine which passes into the bladder.
Kidney tests measure how well the kidneys are working, particularly what types of substances are being released into the urine, at what levels and how quickly. Different tests measure different functions of the kidneys. You should talk with the healthcare team about what tests are being done and for what reasons.
