Tests and diagnosis

By Mayo Clinic Staff

Your doctor is likely to diagnose folliculitis by looking at your skin and reviewing your clinical history. If the usual treatments don't clear up your infection, he or she may use a swab to take a sample of your infected skin. This is sent to a laboratory to help determine what's causing the infection. Rarely, a skin biopsy may be done to rule out other conditions.
