Exams and Tests
During a physical examination, the doctor may find localized swelling. Occasionally, swollen glands (lymph nodes) can be detected near the cellulitis. Your health care provider may mark the edges of the redness with a pen, to see if the redness extends beyond the marked border over the next several days.
Tests that may be used:
- A CBC may show an elevated white blood cell count, and indicates a bacterial infection.
- A blood culture may be performed if generalized infection is suspected.
