AB Examination  of  the  posterior  pharynx  in  patients  with  hematemesis  may  reveal  posterior  epistaxis  as  the  cause.The  Apt–Downey  test  can  differentiate  swallowed  maternal  blood  from  neonatal  GI  bleeding.Vascular  malformations  are  a  rare  but  serious  cause  of  both  upper  and  lower  GI  bleeding.Melena  typically  indicates  proximal  bleeding,  while  hematochezia  is  usually  seen  with  bleeding  from  the  distal  colon  and  rectum.
