risk factors.
If you have one of these risk factors, routine kidney testing may detect problems before symptoms appear.
## How Are Kidney Problems Actually Detected?
Kidney disease is usually evaluated with simple tests.
### Blood Test
A blood test can measure creatinine and estimate how well the kidneys are filtering blood. This is commonly reported as **eGFR**.
### Urine Test
A urine test can detect excess protein, particularly albumin, which may indicate kidney damage.
These tests are much more reliable than trying to diagnose kidney disease from symptoms or skin appearance alone.
