How is a diagnosis of glomerulonephritis made?
The first clues are your signs and symptoms. Finding protein and blood cells in your urine is another sign. Blood tests will help the doctor tell what type of illness you have and how much it has damaged your kidneys.
Sometimes, your doctor will need to do a kidney biopsy by taking a tiny piece of your kidney with a special needle. This will help the doctor plan the best treatment for you.
