Final answer:
The blood urea nitrogen (BUN) and serum creatinine concentration are used to assess kidney function. BUN is an estimation of urea in the blood and creatinine is a waste product that is filtered by the kidneys.
Step-by-step explanation:
The blood urea nitrogen (BUN) and serum creatinine concentration are used to assess kidney function. BUN is an estimation of urea in the blood and creatinine is a waste product that is filtered by the kidneys. Normal BUN levels range from 8-20 mg/dl while normal creatinine levels are 0.8-1.2 mg/dl for males and 0.6-0.9 mg/dl for females. These tests help in diagnosing kidney disorders and monitoring kidney health.
