Eosinophilia : When to see a doctor?

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 check your condition.

Because a separate condition is often the cause of eosinophilia, 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.

However, 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.
