Among the many lab tests used to evaluate kidney function, there are two key measures central to the diagnosis and management of ARF. Serum Creatinine. Serum creatinine (SCr) measures the amount of a substance called creatinine in the blood. Creatinine is a by-product of muscle metabolism that is excreted in urine.

What causes bun to increase in renal failure patients?

A diet high in protein, excessive tissue breakdown, starvation, gastrointestinal bleeding (from proteins in blood) and dehydration (as GFR drops, tubules have more time to reabsorb urea back into the blood) all can cause an increase in BUN. 4 Levels as high as 300 mg/dl have been noted.
