When to see a doctor

Eosinophilia is usually found when your doctor has ordered blood tests to help diagnose a condition you're already experiencing. It's usually not an unexpected finding, but it's possible that it may be discovered simply 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. Your doctor may suggest other tests to check your condition.

It's important to determine what other conditions or disorders you may have. If you get an accurate diagnosis and can receive treatment for any relevant conditions or disorders, the eosinophilia will likely resolve.

If you have hypereosinophilic syndrome, your doctor may prescribe medications, such as corticosteroids. And he or she will want to monitor your health, as this condition may cause significant complications over time.
