Chronic Kidney Disease (CKD) is a long-term condition in which the kidneys become damaged or gradually lose their ability to filter blood effectively. In its early stages, CKD may cause few or no noticeable symptoms, making regular testing important, particularly for people with diabetes, high blood pressure, heart disease, or other risk factors. Kidney health is commonly assessed using blood tests such as estimated Glomerular Filtration Rate (eGFR) and urine tests that measure albumin. Identifying CKD early allows healthcare professionals to investigate its cause, monitor kidney function, manage associated conditions, and address complications. In this article, learn how CKD is detected, why early evaluation matters, and when specialist nephrology care may be appropriate.
