A kidney health panel is a group of blood and urine measurements used to assess how well the kidneys filter waste and maintain fluid and electrolyte balance. It commonly includes blood urea nitrogen and creatinine (with an estimated filtration rate), electrolytes, and urine albumin and creatinine. Clinicians order it to screen for kidney disease, monitor a known condition, or check the effect of medications and chronic illnesses such as diabetes and high blood pressure.

• Blood urea nitrogen (BUN) A waste product that reflects kidney function and hydration.
• Creatinine A muscle waste product used to estimate filtration.
• Estimated glomerular filtration rate (eGFR) A calculated value estimating how well the kidneys filter.
• Sodium An electrolyte involved in fluid balance.
• Potassium An electrolyte important for heart and muscle function.
• Chloride An electrolyte that helps maintain acid-base balance.
• Bicarbonate (carbon dioxide) A marker of acid-base balance.
• Calcium A mineral affected by kidney and parathyroid function.
• Phosphorus A mineral regulated in part by the kidneys.
• Albumin (blood) A protein used in kidney and nutritional assessment.
• Urine albumin A protein whose leakage may signal early kidney damage.
• Urine creatinine Used with urine albumin to form an albumin-to-creatinine ratio.

• People with diabetes or high blood pressure.
• Individuals with a family history of kidney disease.
• Those with swelling, fatigue, or changes in urination.
• People taking medications that can affect kidney function.
• Anyone monitored for chronic kidney disease.

• Fasting may be requested for the blood portion; confirm with the provider.
• A urine sample is often collected at the same visit.
• Stay normally hydrated unless told otherwise.
• Ask whether to hold any medications before testing.
• Avoid heavy exercise right before the draw.

The panel is interpreted as a whole. BUN, creatinine, and eGFR estimate filtration; electrolytes and minerals show how well balance is maintained; and urine albumin with the albumin-to-creatinine ratio can reveal early protein loss. Mild changes may be temporary, while persistent abnormalities may indicate reduced kidney function. Results are a screening and monitoring tool, not a diagnosis. Discuss them with a healthcare provider.
