Kidney Function Test Values Bun And Creatinine. Your protein intake can also shoot up or lower your bun. Kidney function tests target either the blood or urine and measure different aspects of kidney function.
The bun to creatinine ratio generally provides more precise information about kidney function and its possible underlying cause compared with creatinine level alone. They are usually checked with another kidney function marker called bun or blood urea nitrogen. Often doctors will order more than one test at a time to get a broader picture of the.
Two laboratory blood tests that measure kidney function are creatinine and blood urea nitrogen or bun.
Urea is also a metabolic byproduct which can build up if kidney function is impaired. The blood urea nitrogen test doesn t indicate renal insufficiency as well as the serum creatinine since changing factors contributing to fluctuating values unrelated to kidney function may be present. Abnormal levels indicate a kidney or liver related disease or condition. So blood tests can determine the level of bun or blood urea nitrogen in your body as an important indicator of liver and more so kidney health.
