Creatinine renal clearance adjusted for body surface area panel
Calculates how efficiently your kidneys filter creatinine waste from blood.
Why This Biomarker Matters
This is a key indicator of kidney function. Declining clearance suggests kidney disease that may require medical management to prevent further decline and complications.
Overview
This test measures how effectively your kidneys filter waste by calculating creatinine clearance from a 24-hour urine sample and blood test, then adjusting for your body size. Creatinine is a waste product from muscle metabolism that healthy kidneys remove. This calculation (also called GFR estimation) shows kidney function more accurately than blood creatinine alone. Low clearance rates suggest declining kidney function, which requires monitoring and intervention.
