Your doctor will ask about your symptoms and medical history. A physical exam will be done. You will also have a few tests, including:
Creatinine and BUN are waste products that the kidneys usually remove from the blood. When the kidneys are damaged, the creatinine and BUN levels rise in the blood. A simple blood test can measure these levels.
During the filtering process, the kidneys usually return protein to the circulation. With chronic kidney disease, the kidneys allow protein to leak into the urine. Different kinds of proteins can leak into the urine. Albumin is a protein that often appears in the urine of people who have chronic kidney disease caused by high blood pressure or diabetes.
Different tests can be used to check for protein in the urine.
The glomerular filtration rate (GFR) is a measurement of how well the kidneys are processing wastes. Your doctor can calculate the GFR based on your:
The GFR determines the stage of chronic renal disease.
Your doctor may order an ultrasound or a
to evaluate your kidneys, ureters, and bladder. These tests can tell your doctor if a kidney stone, tumor, or other structural problem may have caused the chronic kidney disease.
Your doctor may recommend a kidney biopsy, unless you have small kidneys or have end-stage renal disease. During a kidney biopsy, a small piece of kidney tissue is removed and examined under a microscope. The biopsy can tell how much kidney damage has already occurred. It also may determine the cause of your kidney disease.
Your doctor may order the following tests to determine
if there is an
