Kidney disease frequently progresses silently in patients with longstanding diabetes and hypertension. Routine monitoring of eGFR and microalbuminuria detects renal impairment years before serum creatinine alone signals concern.
Formula & Clinical Methodology
Computed via the 2021 CKD-EPI Creatinine Equation without race modifier: eGFR = 142 × min(Scr/κ, 1)^α × max(Scr/κ, 1)^-1.200 × 0.9938^Age × (1.012 if female). Staging: Stage 1 (≥90 Normal), Stage 2 (60-89 Mild reduction), Stage 3a (45-59 Mild-moderate), Stage 3b (30-44 Moderate-severe), Stage 4 (15-29 Severe), Stage 5 (<15 Kidney failure).
