Tests and diagnosis

By Mayo Clinic Staff

To determine whether you have pink eye, your doctor will ask you about your health history and symptoms and examine your eyes. He or she may also take a sample of eye secretions for laboratory analysis if:

  • You have a very severe case of conjunctivitis
  • Your corneas are affected
  • You've had repeated infections that aren't responding to treatment

If your pink eye is caused by allergies, your doctor may suggest allergy testing to help determine which specific allergens to avoid.
