How do I check if my kidneys are OK?

To check kidney health, your doctor uses simple blood and urine tests, primarily the eGFR blood test (checks creatinine levels to estimate filtering rate) and the uACR urine test (checks for albumin/protein leak), plus a standard urinalysis for overall function, with imaging like ultrasound or CT scans used for physical issues like stones or cysts. Regular check-ups are key, especially if you have risk factors, to catch problems early.
