The Blood Urea Test — also known as BUN (Blood Urea Nitrogen) — at Pamel Laboratories is a key diagnostic test that measures the amount of urea nitrogen in your blood. Urea is a waste product formed when your body breaks down protein and is eliminated through the kidneys. This test is primarily used to assess kidney function and monitor conditions affecting the kidneys, liver, or overall fluid balance.
It is commonly ordered for routine health checkups, monitoring of chronic diseases, or evaluation of symptoms such as fatigue, swelling, or changes in urination.
What the Test Measures:

Part of routine renal function panels or pre-surgical testing
