What this test is

The Kidney Function Test Panel is a group of laboratory tests that provide a comprehensive look at your renal system. It measures various substances in your blood and urine to detect potential kidney problems.

What it measures

• Blood Urea Nitrogen (BUN) — reflects kidney's ability to filter waste
• Creatinine — measures a waste product from muscle activity, filtered by kidneys
• Albumin — a protein that can indicate kidney damage if found in urine
• Sodium — an electrolyte important for fluid balance
• Potassium — an electrolyte crucial for heart and nerve function
• Chloride — an electrolyte that helps maintain fluid balance
• Carbon Dioxide (CO2) — reflects the body's acid-base balance
• Calcium — a mineral affected by kidney function
