The most important tests for renal function are contained in a comprehensive metabolic panel. This will usually include an estimated GFR glomerular filtration rate which will let you know how well your kideneys are functioning. Your creatinine clearance, bun, and GFR should be in the comprehensive metabolic panel. Speak to your physcian also about ordering a spot urine for microalbumin if your kideney function is diminished.
