Final answer:
The two main biomarkers used to assess kidney function are blood urea nitrogen (BUN) and creatinine.
Step-by-step explanation:
The two main biomarkers used to assess kidney function are blood urea nitrogen (BUN) and creatinine.
Blood urea nitrogen (BUN) is an estimation of urea in the blood and serves as an indicator of kidney function. Normal BUN levels range from 8-20 mg/dl.
Creatinine is a waste product that is produced by the body and eliminated by the kidneys. The level of creatinine in the blood is a reliable indicator of kidney function, with normal levels ranging from 0.8-1.2 mg/dl for males and 0.6-0.9 mg/dl for females.
