What is Eosinophils?
An absolute eosinophil count is a blood test that measures the number of one type of white blood cells called eosinophils. Eosinophils become active when you have certain allergic diseases, infections, and other medical conditions.
How the Test is Performed
Most of the time, blood is drawn from a vein on the inside of the elbow or the back of the hand. The site is cleaned with an antiseptic. The health care provider wraps an elastic band around your upper arm to make the vein swell with blood.

Next, the provider gently inserts a needle into the vein. The blood collects into an airtight tube attached to the needle. The elastic band is removed from your arm. The needle is then removed and the site is covered to stop bleeding.

In infants or young children, a sharp tool called a lancet may be used to prick the skin. The blood collects in a small glass tube, or onto a slide or test strip. A bandage is put on the spot to stop bleeding.

In the lab, the blood is placed on a microscope slide. A stain is added to the sample. This causes eosinophils to show up as orange-red granules. The technician then counts how many eosinophils are present per 100 cells. The percentage of eosinophils is multiplied by the white blood cell count to give the absolute eosinophil count.
How to Prepare for the Test
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.

Medicines that may cause you to have an increase in eosinophils include:
  • Amphetamines (appetite suppressants)
  • Certain laxatives containing psyllium
  • Certain antibiotics
  • Interferon
  • Tranquilizers
How the Test will Feel
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.
Why the Test is Performed
You will have this test to see if you have abnormal results from a blood differential test. This test may also be done if the provider thinks you may have a specific disease.

This test may help diagnose:
  • Acute hypereosinophilic syndrome (a rare, but sometimes fatal leukemia-like condition)
  • An allergic reaction (can also reveal how severe the reaction is)
  • Early stages of Addison disease
  • Infection by a parasite
  • Vasculitis
Normal Results
Normal eosinophil count is less than 500 cells per microliter (cells/mcL).
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 the results of these tests. Some laboratories use different measurements or may test different specimens.
What Abnormal Results Mean
A high number of eosinophils (eosinophilia) are often linked to a variety of disorders. A high eosinophil count may be due to:
  • Adrenal gland deficiency
  • Allergic disease, including hay fever
  • Asthma
  • Autoimmune diseases
  • Eczema
  • Fungal infections
  • Hypereosinophilic syndrome
  • Leukemia and other blood disorders
  • Lymphoma
  • Parasite infection, such as worms
A lower-than-normal eosinophil count may be due to:
  • Alcohol intoxication
  • Overproduction of certain steroids in the body (such as cortisol)
Risks
Risks from having blood drawn are slight, but may include:
  • Excessive bleeding
  • Fainting or feeling lightheaded
  • Hematoma (blood accumulating under the skin)
  • Infection (a slight risk any time the skin is broken)
