Tests and diagnosis
By Mayo Clinic staffTo 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.
