If you’re referring to the headline “9 Warning Signs Your Kidneys Are Failing | Tests to Avoid Dialysis,” there is an important correction: kidney disease often causes no symptoms in its early stages, so testing is much more useful than waiting for warning signs.

9 possible warning signs of advanced kidney disease
Swelling of the feet, ankles, legs, hands, or face
Foamy urine, which can indicate excess protein
Blood in the urine
Changes in urination, such as going much more or less frequently
Persistent fatigue or weakness
Loss of appetite, nausea, or vomiting
Persistent itching or very dry skin

These symptoms don’t prove that your kidneys are failing. They can occur with many other conditions.
The 2 most important kidney tests
1. eGFR — blood test
Creatinine is measured in the blood and used to estimate how well the kidneys filter. An eGFR below 60 may indicate kidney disease when persistent; 15 or lower is considered kidney failure.

2. uACR — urine test
The urine albumin-to-creatinine ratio detects albumin (protein) leaking through damaged kidney filters. 30 mg/g or less is considered normal; above 30 mg/g may indicate kidney disease. Abnormal results are often repeated for confirmation.

Can you “avoid dialysis”?
There is no test that guarantees you can avoid dialysis. However, finding chronic kidney disease early and treating its cause can slow progression. Diabetes, high blood pressure, heart disease, and family history of kidney failure are important reasons to ask about kidney testing.

The key takeaway: Don’t wait until you develop symptoms. If you’re at increased risk, ask your clinician about eGFR + uACR—these two tests provide a much clearer picture of kidney health than symptoms alone.
