Kidney Stone Analysis
Kidney stones are small, pebble-like pieces of material that form in one or both of your kidneys. Your kidneys are two bean-shaped organs just below your rib cage. They keep your body's balance of water, minerals, and salts by removing waste to make urine (pee). Kidney stones form when you have high levels of some minerals or salts in your urine (pee). Many things may increase your risk of kidney stones. These can include your diet, some health conditions, and some supplements or medicines.
What it is for
A kidney stone analysis is used to find out what your kidney stone is made of. This helps your provider understand why the stone formed and what will help stop more stones from forming in the future. This is important because once you've had a stone, you're likely to get another one. Source: MedlinePlus, National Library of Medicine. Medical test information is public domain.
