magent
Richards 1990 BUN/creatinine ratio as bun_mg_dl / creatinine_mg_dl, rounded to one decimal. A ratio of 36 or greater suggests upper gastrointestinal bleeding. A ratio below 36 is not helpful in locating the source and is not a lower-GI class. Provide creatinine_mg_dl (0.1-20) or creatinine_umol_l (9-1768), not both. Not a diagnosis, endoscopy order, or Blatchford urea band. magent does not locate a bleed.
