Why is my eosinophil count high

It is not uncommon for the elevated count to be transient and resolve without treatment. Let's review some of the causes now.

Like most blood disorders, eosinophilia is identified on complete blood count CBC. Eosinophils are one of the white blood cells and are found in the portion of the CBC called the differential. The differential reports how many of each type of white blood cells neutrophil, lymphocyte, monocyte, eosinophil, and basophil are present in the blood.

After identification of eosinophilia, your healthcare provider will start working towards identifying the cause, sometimes this requires referral to a hematologist. Eosinophilia can be categorized by the number of eosinophils absolute eosinophil count. Determining the cause of your eosinophilia will be based on your symptoms.

Diagnosis requires a biopsy of the esophagus. Many of the parasite infections are diagnosed by taking stool samples and testing them. There may not be a test to determine if a medication is the cause of your eosinophilia.

If your eosinophil count returns to normal after discontinuing the medications, it is usually presumed that the medication was the cause. Similar to what diagnostic tests may be needed, treatment is determined by the cause of eosinophilia. Hypereosinophilia is a scary-sounding word. Fortunately, for most people with this condition, it is transient and requires little to no treatment. For some, diagnosis and treatment may require referral to a specialist.

If you have additional concerns, make sure to discuss them with your physician. Colds and Many parasites Overview of Parasitic Infections A parasite is an organism that lives on or inside another organism the host and benefits for example, by getting nutrients from the host at the host's expense.

Cancers that cause eosinophilia include Hodgkin lymphoma Hodgkin Lymphoma Hodgkin lymphoma is a type of lymphoma distinguished by the presence of a particular kind of cancer cell called a Reed-Sternberg cell.

The cause is unknown. Lymph nodes enlarge but are usually White blood cells develop from stem cells in the bone marrow.

Sometimes the development goes awry If the number of eosinophils is only slightly elevated, people usually do not have symptoms, and the high number of eosinophils in the blood is only discovered when a complete blood count is done for other reasons.

However, sometimes, particularly when the number of eosinophils is very high, the increased number of eosinophils inflames tissues and causes organ damage. The heart, lungs, skin, and nervous system are most often affected, but any organ can be damaged.

Symptoms are related to the organ affected. Accordingly, eosinophilic disorders are diagnosed according to the location where the levels of eosinophils are elevated:. Eosinophilic esophagitis Eosinophilic Esophagitis Eosinophilic esophagitis is an inflammatory disorder in which the wall of the esophagus becomes filled with large numbers of eosinophils, a type of white blood cell.

This disorder may be caused Eosinophilic pneumonia Eosinophilic Pneumonia Eosinophilic pneumonia comprises a group of lung diseases in which eosinophils a type of white blood cell appear in increased numbers in the lungs and usually in the bloodstream.

Certain disorders Often, people are first tested and treated for more common causes of their symptoms. For example, they might undergo testing for infection and even receive antibiotics even though no infection is found. The technician then counts how many eosinophils are present per cells. The percentage of eosinophils is multiplied by the white blood cell count to give the absolute eosinophil count.

Most of the time, adults do not need to take special steps before this test. Tell your provider the medicines you are taking, including the ones without a prescription. Some drugs may change the test results. You may feel slight pain or a sting when the needle is inserted. You may also feel some throbbing at the site after the blood is drawn.

Normal value ranges may vary slightly among different laboratories. Talk to your provider about the meaning of your specific test results. The example above shows the common measurements for results of these tests. Some laboratories use different measurements or may test different specimens. A high number of eosinophils eosinophilia are often linked to a variety of disorders.
