CPE-003 · synthetic case CKD-EX-05
G2 without a marker of kidney damage
A documented CKD label, G2, with a normal UACR and no other marker.
Purpose: A documented CKD label, G2, with a normal UACR and no other marker.

What the engine reports
Detected clinical pattern
CKD Not Demonstrated by Available Data
G1 or G2 alone does not establish CKD without a marker of kidney damage.
- Chronicity: Chronicity confirmed (≥3 months)
Clinical summary
G2 without a marker of kidney damage does not establish CKD. Physician adjudication required.
Why this pattern was identified
- Albuminuria. UACR 12 mg/g, category A1 (<30 mg/g).
Why it matters
The result is placed in context so the physician can see what is established, what is provisional and what is missing.
Evidence and rule trace · 3 rules
CGA-001Assign G category from selected indexed eGFR
Inputs: G category G2 (documented)
G2 (60–89 mL/min/1.73 m²)
CGA-003G1/G2 requires damage marker to label CKD
Inputs: G2 without a marker of kidney damage

Evidence
- R1 · KDIGO 2024 Clinical Practice Guideline for the Evaluation and Management of Chronic Kidney Disease. Kidney Disease: Improving Global Outcomes (KDIGO), 2024.
Physician adjudication required. Clinical decision support for physician review. Criteria-based status is not a probability. Findings require physician adjudication and correlation with the complete clinical context. Validation-only release: not for production clinical use.
