Patients can be tested for kidney disease in three ways:
A urine test that looks for blood or protein in your urine, which could be a sign of decreased kidney function.
A blood pressure test will determine if your kidney health should be tested by a doctor. High blood pressure can cause kidney disease, but kidney disease can also cause high blood pressure.
Estimated glomerular filtration rate (eGFR) is a sign of how well kidneys are cleaning blood. This blood test measures how much creatinine (a type of waste) is in the blood, which allows a provider to calculate the filtration rate of the kidneys.
