A routine blood test is likely to pick up chronic kidney disease before you experience any symptoms. This may have been done as part of a health assessment or because of another condition, or because you already suffer from one of the common cause listed previously.
The important signs of kidney damage are :
- Reduced kidney function, which is detected by a blood test that measures your estimated glomerular filtration rate
- An excess of protein in the urine
- Blood in the urine that is coming from the kidney itself, not the ureter or bladder
- Abnormal appearance of the kidneys, seen on a scan
