*** BUN level is often elevated in patients with upper GI bleeds because of bacterial breakdown of HB in the GI tract that results in absorption of UREA,
A BUN level MORE THAN 40 in the presence of NORMAL CREATININE level indicate GI bleed.It can also occur with administration of STEROIDS
Only ELEVATION OF CREATININE without BUN --- Drug administration - TMP/SMX,CIMETIDINE
