When to see a doctor
By Mayo Clinic staffEosinophilia is usually found when your doctor has ordered blood tests to help diagnose a condition you're already experiencing. It's not often an unexpected finding or simply discovered by chance.
Talk to your doctor about what these results mean. Evidence of blood or tissue eosinophilia and results from other tests may indicate the cause of your illness, or your doctor may suggest other tests to assess your condition.
