Common questions

How do I know if I have kidney disease?

Early kidney disease usually has no symptoms — most people feel completely fine. The only reliable way to check is two simple tests: a blood test for eGFR (how well your kidneys filter) and a urine test for protein (ACR). Our free eGFR tool gives you an instant estimate to discuss with a clinician.

Is KidneyGlobal free to use?

Yes. Reading the Kidney Wiki, using the health tools, and browsing verified specialists is free. Paid consultations and premium app features are optional. KidneyGlobal is a non-profit initiative funded mainly by donations.

Are the doctors on KidneyGlobal verified?

Specialists marked „Verified” have had their licence, credentials and specialty confirmed before their profile goes live. Every published article also shows who medically reviewed it and when.

Can KidneyGlobal diagnose my condition?

No. Our content and calculators are educational and don’t diagnose or replace medical advice. They help you understand your numbers and prepare for a conversation with a qualified clinician.
