  • Biopsy: A skin biopsy may be necessary to determine the cause of the blisters.
  • Blood tests: Blood tests may be performed to check for underlying medical conditions such as infections or autoimmune disorders.
  • Culture or swab: A culture or swab of the blister may be taken to determine if an infection is present.
  • Allergy testing: If an allergic reaction is suspected, allergy testing may be performed to determine the allergen responsible.
  • Viral studies: If a viral infection is suspected, tests may be done to identify the virus responsible.
  • Imaging studies: X-rays or MRIs may be done to determine if an underlying bone or joint issue is causing the blisters.
