Hypereosinophilic syndrome care at Mayo Clinic

Your Mayo Clinic care team

Hypereosinophilic syndrome (HES) can affect many parts of your body. Mayo Clinic's HES care team includes specialists in allergic diseases, skin diseases (dermatology), digestive disorders (gastroenterology), brain and nervous system disorders (neurology), blood disorders (hematology), and laboratory medicine (pathology).

Having all of this subspecialized expertise in a single place, focused on you, means that you're not just getting one opinion — care is discussed among the team, appointments are scheduled in coordination, and highly specialized HES experts are all working together to determine what's best for you.

Advanced diagnosis and treatment

HES is a diverse and complex syndrome. Extensive testing is often needed to refine diagnosis and assess potential damage to organs.

At Mayo Clinic, a detailed itinerary for appointments, tests and procedures helps make the best use of your time. Mayo Clinic technicians run all tests and labs themselves, which means tests taken in the morning can often be reviewed the same afternoon. Mayo's collaborative approach means two or three days often yields the diagnosis and care insights that could take weeks in many other institutions.

Expertise and rankings

Hypereosinophilic syndrome is a rare disorder, so it can be difficult to find a doctor who has much experience in treating it. Doctors at Mayo Clinic see more than 1,000 people with HES each year.

Costs and insurance

Mayo Clinic works with hundreds of insurance companies and is an in-network provider for millions of people.

In most cases, Mayo Clinic doesn't require a physician referral. Some insurers require referrals, or may have additional requirements for certain medical care. All appointments are prioritized on the basis of medical need.
