HIGH Chronic kidney disease — IRIS Stage 2
Creatinine 2.1 mg/dL and SDMA 18 µg/dL confirmed on two samples taken two weeks apart. Staging CKD using the IRIS system is essential — it directs management decisions and establishes a prognostic baseline; early-stage identification is associated with markedly longer survival times.[1] Substage by UPC ratio and systolic blood pressure before finalizing the treatment plan.
