Final answer:
The normal Blood Urea Nitrogen (BUN) range is between 8 to 25 mg/100 mL. It serves as an indicator of kidney function and is part of the assessment of renal function along with plasma creatinine and other markers.
Step-by-step explanation:
The normal range for Blood Urea Nitrogen (BUN) is generally considered to be between 8 to 25 mg/100 mL. This range is used to assess renal functions along with other markers such as plasma creatinine. Blood urea is synthesized in the liver and plays a critical role in the excretion of nitrogenous wastes. The BUN value is an estimated concentration of urea in the blood and serves as an important indicator of kidney function.
When evaluating a patient's blood chemistry for renal function, elevated BUN levels may indicate renal impairments or other conditions affecting the kidneys. It is crucial to interpret these levels in conjunction with other diagnostic tests and the patient’s clinical presentation.
