Laboratory tests are usually unhelpful unless complications are present (eg, upper gastrointestinal [GI] hemorrhage). The following may be considered:

  • Complete blood count (CBC) in patients with neutropenia or immunosuppression
  • CD4 count and HIV test in patients with risk factors for HIV
  • Systemic autoimmune disease workup as indicated by the underlying disease
