What Is a Kidney Function Test?
A kidney function test is a group of blood tests used to assess how well your kidneys are working. Your kidneys help remove waste products from the blood, regulate fluids, balance electrolytes, and support healthy blood pressure.
Many kidney conditions develop gradually and may not cause noticeable symptoms early. Regular testing helps detect kidney problems early, when treatment is most effective.
