Final answer:
A blood urea nitrogen level of 32 mg/dl is above the normal range, which generally spans 8-20 mg/dl. High BUN levels can indicate uremia, associated with kidney disorders and may require medical treatment.
Step-by-step explanation:
A blood urea nitrogen (BUN) level of 32 mg/dl is considered outside the normal range. The typical BUN range is 8-20 mg/dl, and urea concentration in the blood is normally maintained at 15-40 mg/dl. Levels above the normal range may indicate an increase in blood urea, also known as uremia, which can be classified into pre-renal, renal, and post-renal causes. Renal uremia occurs when blood urea levels exceed 300 mg/dl due to kidney disorders. It is essential to monitor and manage blood urea levels to prevent toxicity and maintain renal health.
