Kidney Tests
A kidney function test shows whether the organs are properly regulating the amount of water and salts we have in our body, and whether the kidneys are efficiently filtering blood and aiding in eliminating waste products. Further, renal function tests measure the levels of urea, creatinine, and certain dissolved salts that can help determine whether or not the kidneys are functioning properly and paint a picture of your overall health. Order an online kidney blood test today and take the first step in preventing and diagnosing renal disease.
