The Kidney Health Panel goes beyond basic kidney markers to provide a thorough assessment of renal function. The Renal Panel and CMP evaluate electrolytes, BUN, and creatinine. Cystatin C provides a more accurate GFR estimate than creatinine alone — especially valuable for people with high or low muscle mass. A complete urinalysis screens for protein, blood, and other abnormalities that indicate kidney damage. This panel is ideal for anyone with diabetes, hypertension, or a family history of kidney disease.
Comprehensive kidney evaluation: Renal Panel (BUN, creatinine, eGFR, electrolytes) + Microalbumin (early kidney damage) + Cystatin C (more accurate eGFR than creatinine alone). Catches kidney disease years before standard labs.
Anyone with diabetes, hypertension, family history of kidney disease, on nephrotoxic medications (NSAIDs long-term, lithium, ACE/ARBs), recurrent kidney stones, or age 60+ for baseline.
