A comprehensive 11-biomarker panel that evaluates kidney health by measuring waste filtration, electrolyte balance, and mineral levels.
The Renal Function Panel provides a thorough assessment of your kidney health and function. Your kidneys filter about 200 quarts of blood daily, removing waste products and excess fluids while maintaining critical electrolyte and mineral balance.
This panel measures key markers of kidney filtration (creatinine, BUN, eGFR), electrolyte balance (sodium, potassium, chloride, CO2), and mineral status (calcium, phosphorus). Together, these markers reveal how efficiently your kidneys are working.
Kidney disease is often called a "silent disease" because it can progress without symptoms until significant damage occurs. Approximately 1 in 7 Americans has chronic kidney disease, and many don't know it. Regular kidney testing is especially important if you have diabetes, high blood pressure, or a family history of kidney disease.

What's Measured
What This Test Measures
This panel measures 11 biomarkers: Creatinine and BUN assess waste filtration. eGFR (estimated Glomerular Filtration Rate) calculates overall kidney function. Electrolytes (sodium, potassium, chloride, CO2) show fluid and acid-base balance. Calcium, phosphorus, and albumin round out the mineral and protein assessment.
Who Should Consider This Test
People with diabetes or high blood pressure, those taking medications that affect kidneys (NSAIDs, certain blood pressure medications), individuals with family history of kidney disease, those with frequent urinary symptoms, and anyone wanting a baseline kidney health assessment.

When to Get Tested
No fasting required. Can be tested any time of day. Stay normally hydrated before testing.
Understanding Your Results
Normal ranges: Creatinine 0.7-1.3 mg/dL (men), 0.6-1.1 mg/dL (women). BUN 7-20 mg/dL. eGFR >90 mL/min is normal, 60-89 is mildly decreased, <60 may indicate chronic kidney disease. Electrolyte imbalances may indicate dehydration or kidney dysfunction.
What to Expect
After placing your order, you'll receive an email from Rupa Health (our lab order partner) within 24 business hours to sign a consent form and schedule your blood draw at a Quest Diagnostics location.
The blood draw typically takes just a few minutes. Results are usually available within 1 business days and will appear in your secure Justlabs dashboard.
Our results include reference ranges and easy-to-understand indicators showing whether your values are within normal limits.
