Diagnostic Tests for Eczema

Diagnostic Test list for Eczema:

The list of diagnostic tests mentioned in various sources as used in the diagnosis of Eczema includes:

  • Bacterial culture - if suspect secondarily infected areas (look for pus-filled lesions, crusting and weepiness).
  • Viral culture - if suspect Herpes Simplex virus infected areas.
  • Blood tests
    • Radioallergosorbent testing (RAST) - to test for specific allergens that may be triggering eczema ( 90% relevant if negative, but only 20% relevant if positive).
    • Ig E levels are increased
  • Patch testing - for allergic contact dermatitis.
  • Skin biopsy, may occasionally be warranted (but diagnosis is usually on history and physical findings)
  • Physical exam
  • Skin scratch/prick tests - need careful interpretation.
  • Blood tests for airborne allergens - often not very useful for diagnosis.
  • Eosinophil levels
  • IgE levels
