2021 CKD-EPI Creatinine Equation (Race-Free): This updated formula no longer uses race as a variable, improving equity and accuracy. It uses serum creatinine, age, and sex to estimate eGFR (mL/min/1.73 m²).

Understanding eGFR & CKD

eGFR (estimated Glomerular Filtration Rate) is the best measure of kidney function. The 2021 CKD-EPI equation was updated to remove race as a variable, producing more equitable and accurate estimates for all patients. A single eGFR below 60 for more than 3 months indicates Chronic Kidney Disease (CKD).

Why Test eGFR?

CKD often has no symptoms in early stages. Regular eGFR testing allows early detection, giving you time to slow or even reverse kidney decline with proper treatment.

Ayurvedic Approach

Ayurveda focuses on root-cause treatment — detoxification, herbal therapy, and lifestyle changes to restore kidney health naturally, without harsh side effects.

Improving eGFR

With Dr. Dhankhar's specialised Ayurvedic protocols, many patients have seen significant improvements in their eGFR and quality of life, even at advanced stages of CKD.
