Core Tip	Differentiation of upper vs lower gastrointestinal (GI) bleeding is crucial. Laboratory test variables were investigated for their ability to distinguish upper from lower GI bleeding from retrospective analysis. Total protein, hemoglobin, and lactate dehydrogenase were lower and blood urea nitrogen (BUN) was higher in patients with upper GI bleeding. The threshold BUN value for distinguishing upper from lower GI bleeding was 21.0 mg/dL, with a specificity of 93.0%.
