How is bullous pemphigoid diagnosed?

Your doctor will usually begin an exam to see if you have bullous pemphigoid by asking a series of questions, such as:

  • When did your symptoms begi?
  • Do your blisters have pus or blood?
  • Have you had a fever?
  • Have you started any new medications?

Your doctor may then perform tests to confirm the diagnosis. These include blood tests and a skin biopsy.
