Tests and diagnosis

By Mayo Clinic staff

To diagnose a staph infection, your doctor will:

  • Perform a physical exam. During the exam, your doctor will closely examine any skin lesions you may have.
  • Collect a sample for testing. Most often, doctors diagnose staph infections by checking a tissue sample or nasal secretions for signs of the bacteria.
