The doctor will ask about your symptoms and health past. A physical exam will be done.
Tests may include:
- Blood tests—to look for:
- Glomerular filtration rate (GFR)—Measures how well the kidneys are filtering wastes. GFR drops as the kidneys fail.
- Increase in wastes in the blood. Items measured may include creatine and urea. The amount of wastes in the blood goes higher as the kidneys fail.
- Changes of substances in the blood that are normally controlled by the kidneys. This may include calcium, phosphorus, parathyroid hormone, blood electrolytes, and potassium.
- Urine tests—to look for:
- Excess protein in the urine. Damaged kidneys let more protein pass into urine than healthy kidneys.
- Amount of urine that is made. 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
- CT scan.
- Kidney biopsy—Tissue samples are taken and looked at in a lab. It may help find a cause or extent of damage.
