Diagnostic Approach
Diagnosis is often based on direct observation of blood in the stool or vomit. This can be confirmed with a fecal occult blood test. Differentiating between upper and lower bleeding in some cases can be difficult. The severity of an upper GI bleed can be judged based on the Blatchford score or Rockall score. The Rockall score is the more accurate of the two. AS of 2008 there is no scoring system useful for lower GI bleeds.

Famous quotes containing the word approach:
“The white man regards the universe as a gigantic machine hurtling through time and space to its final destruction: individuals in it are but tiny organisms with private lives that lead to private deaths: personal power, success and fame are the absolute measures of values, the things to live for. This outlook on life divides the universe into a host of individual little entities which cannot help being in constant conflict thereby hastening the approach of the hour of their final destruction.”
—Policy statement, 1944, of the Youth League of the African National Congress. pt. 2, ch. 4, Fatima Meer, Higher than Hope (1988)
