The doctor will ask about your symptoms and health past. A physical exam will be done. Tests can find if chronic kidney disease is in the end-stage.

Tests may include:

  • Blood tests—To look for:
    • Glomerular filtration rate (GFR)—Measures how well the kidneys are filtering wastes. GFR differs based on gender, age, body size, and blood creatinine level. ESRD is kidney function less than 15% of normal.
    • Excess wastes such as creatinine and urea. The amount of wastes in the blood goes higher as the kidneys fail.
    • To check levels of calcium, phosphorus, parathyroid hormone, blood electrolytes, and potassium.
  • Urine tests—This may be collected over a 24-hour period. The test will look for the amount of protein that is being leaked into the urine. The amount of urine made is also important. Little or no urine is made as the kidneys fail.
  • Imaging tests look for a cause of sudden changes in how the kidneys work. They can also look at the size and shape of the kidneys. Tests may be done with ultrasound, MRI scan, or CT scan.
  • Kidney biopsy—Tissue samples are taken and looked at in a lab. It may help find a cause or extent of damage.
