CKD-EPI 2021 eGFR Calculator
Estimate Glomerular Filtration Rate ($mL/min/1.73m^2$) and determine KDIGO Chronic Kidney Disease staging for adult clinical evaluation.
eGFR between 60 and 89 mL/min/1.73m². Mild reduction, monitor during annual exams.
Medsy tracks eGFR trends across patient visits and flags medication dosage warnings automatically.

| Stage | eGFR Range ($mL/min/1.73m^2$) | Clinical Description | Action Recommendation |
|---|---|---|---|
| G1 | ≥ 90 | Normal or High Function | Monitor & control risk factors |
| G2 | 60 – 89 | Mildly Decreased | Evaluate CKD progression risk |
| G3a | 45 – 59 | Mildly to Moderately Decreased | Review medication dosing |
| G3b | 30 – 44 | Moderately to Severely Decreased | Monitor renal complications |
| G4 | 15 – 29 | Severely Decreased | Referral to Nephrologist |
| G5 | < 15 | Kidney Failure | Renal replacement / Dialysis planning |
Why standardizing on 2021 CKD-EPI is vital
In 2021, the National Kidney Foundation (NKF) and American Society of Nephrology (ASN) joint task force recommended immediate adoption of the 2021 race-free CKD-EPI creatinine equation to ensure unbiased renal assessment across diverse patient populations.
Renal Medication Adjustment Warning
When eGFR drops below 60 $mL/min/1.73m^2$, clinicians should evaluate renal clearance for medications including Metformin, NSAIDs, SGLT2 inhibitors, DOACs, and certain antibiotics to prevent drug toxicity.
