Diagnosis of Kidney failure
After checking for symptoms, a number of tests can help diagnose kidney failure:
- Blood test - to find out if waste substances have been filtered out
- Urine test – to see if there is blood or protein in the urine.
- Kidney scans such as MRI scan, CT scan or ultrasound – to find if there are any unusual blockages in urine flow. When kidney disease is advanced, the kidneys are shrunken, have an uneven shape and are firm to touch.
- Kidney biopsy – taking a small sample of tissue to test the cells and look for damage
- Calculating the glomerular filtration rate – to check how efficiently the kidneys are filtering waste, in particular a substance called creatinine.
