Diagnosis Of A Skin Infection
Your dermatologist may use one or a combination of the following methods to diagnose an ongoing skin infection.
Your doctor will take your medical history and ask about your symptoms and their timeline and possible risk factors.
Oftentimes, a good physical examination can already help the doctor identify the type of skin infection based on the appearance and location of the bumps, rashes, or lesions.
Skin Culture or Biopsy
This is a test to identify what microorganism is causing your skin infection by swabbing or scraping your skin or wound to take a sample and looked into a microscope.
Blood tests such as a complete blood count can give a general picture of whether your skin infection is caused by bacteria, viruses, or fungi.
