If the diagnosis of peptic ulcer disease is suspected, obtaining a complete blood cell (CBC) count, liver function tests (LFTs), and levels of amylase and lipase may be useful. CBC count and iron studies can help detect anemia, which is an alarm signal that mandates early endoscopy to rule out other sources of chronic gastrointestinal (GI) blood loss.
