Evaluate Initial Results
Before continuing, please consider:
- Low eGFR (estimated glomerular filtration rate) in such scenarios may reflect acute kidney injury (AKI) and require more rapid evaluation.
- Measure with serum eGFR and urine albumin/creatinine ratio (ACR).
Are the initial results ABNORMAL? (ABNORMAL = eGFR < 60ml/min/1.75m2 and/or urine ACR ≥ 3mg/mmol)
- CKD detection should be done in the absence of acute intercurrent illness or self-limited illness.
The result indicates CKD may be present.
Next Steps
- Repeat eGFR in 3 months, or sooner if clinical concern dictates (i.e., rapid decline from previous eGFR result or very low eGFR).
- Repeat urine ACR 1 or 2 more times over the next 3 months.
Notes
- At least 2 out of 3 random urine ACRs must be elevated (≥ 3) to confirm a person has chronic kidney disease.
- If a previous abnormal eGFR and/or urine ACR result is available within the last year of identifying a person with risk factors for CKD, then repeat the 2 measurements to confirm diagnosis (the 2 sets of measurements must be at least 3 months apart).
- Always consider reversible causes before re-measuring (i.e., recent treatments with non-steroidal anti-inflammatory drugs (NSAIDs), recent use of contrast dye for diagnostic imaging, benign prostatic hyperplasia (BPH)/urinary retention).
Once eGFR and urine ACR results are received, please re-visit the KidneyWise tool and go to Confirm Diagnosis.
The person likely does not have CKD.
