![]() ![]() If many eosinophils are found, a molecular genetic analysis should be done to test for a genetic mutation that makes an abnormal protein known as FIP1-like-1/platelet-derived growth factor alpha or FIP1L1-PDGFRa. Your doctor may recommend running laboratory tests on the eosinophils to identify specific genes, proteins, and other factors unique to the leukemia. Acute eosinophilic leukemia is not covered in this article and is treated similarly to AML. Many immature cells, called blasts, in the bone marrow are a sign of acute rather than chronic eosinophilic leukemia. Other types of anesthesia (medication to block awareness of pain) may also be used. The skin in that area is usually numbed with medication beforehand. A common site for a bone marrow aspiration and biopsy is the pelvic bone, which is located in the lower back by the hip. A pathologist is a doctor who specializes in interpreting laboratory tests and evaluating cells, tissues, and organs to diagnose disease. A bone marrow biopsy is the removal of a small amount of solid tissue using a needle.Ī pathologist then analyzes the sample(s) to determine the number and type of abnormal cells. A bone marrow aspiration removes a sample of fluid with a needle. Bone marrow has both a solid and liquid part. These 2 procedures are similar and often done at the same time to examine the bone marrow. If the blood contains many eosinophils (see criteria above), eosinophilic leukemia is suspected.īone marrow aspiration and biopsy. A CBC measures the number of different types of cells in a person's blood. The diagnosis of eosinophilic leukemia begins with a test called a complete blood count (CBC). ![]() In addition to a physical examination, the following tests may be used to diagnose eosinophilic leukemia:īlood tests. Problems with the functioning of a person’s organs because of the eosinophilia No parasitic infection, allergic reaction, or other causes of eosinophilia The main criteria for diagnosing eosinophilic leukemia are:Īn eosinophil count in the blood of 1.5 x 10 9 /L or higher that lasts over time Your doctor may consider these factors when choosing a diagnostic test: Not all tests listed below will be used for every person. This list describes options for diagnosing eosinophilic leukemia. Doctors may also do tests to learn which treatments could work best. Although a patient’s signs and symptoms may cause a doctor to suspect eosinophilic leukemia, it is diagnosed only by testing a patient’s blood and bone marrow.
