The basic metabolic profile (BMP) is useful in evaluating for renal comorbidity in cases of suspected upper gastrointestinal (GI) bleeding (UGIB); however, blood in the upper intestine can elevate the BUN (blood urea nitrogen) level as well. Measurement of coagulation parameters is necessary to assess for continued bleeding. Abnormalities should be corrected rapidly.

The BUN-to-creatinine ratio increases with UGIB. A ratio of greater than 36 in a patient without renal insufficiency is suggestive of UGIB.
