Methodology · worked example, guidelines & full notes
CKD requires abnormalities to persist ≥ 3 months.
When to use
the diagnosis requires abnormalities to persist ≥ 3 months.
How it works
eGFR stages G1–G5 × albuminuria A1 (< 30), A2 (30–300), A3 (> 300 mg/g) → low/moderate/high/very-high risk per the KDIGO grid.
Key points
- CKD requires abnormalities to persist ≥ 3 months.
- G1–G2 with A1 needs another marker of kidney damage to diagnose CKD.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| eGFR | 45 mL/min/1.73m² |
|---|---|
| Urine albumin/creatinine ratio (ACR) | 250 mg/g |

FAQ
Frequently asked questions
- What are the limits and cautions when using CKD Staging & Referral (KDIGO)?
- For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
- Does CKD Staging & Referral (KDIGO) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is CKD Staging & Referral (KDIGO) calculated in practice? Can you show a worked example?
- Inputs: eGFR 45 mL/min/1.73m², Urine albumin/creatinine ratio (ACR) 250 mg/g → Result: CKD risk stratum High risk（Stage: G3a A2, eGFR stage: G3a (45–59), Albuminuria stage: A2 (30–300 mg/g)）
