Why should I bother getting diagnosed?

Because your health is important! CKD can be managed once it’s caught. Conditions like anemia, bone disease, and heart problems can be caught early too. Patients with an extremely low GFR (less than 30 mL/min) are toeing the line of critical condition and should start getting educated about dialysis and kidney transplant.

Most patients are diagnosed through routine bloodwork which includes your creatinine and GFR. Since CKD often doesn’t have symptoms, the best advice is to keep current with your annual health checkups.
