EOS (Eosinophils) Blood Test (Labcorp)
This test measures Eosinophils in a blood sample. Eosinophils are a type of white blood cell. WBC's are produced in the bone marrow and protect the body from bacteria, viruses, and parasites. Eosinophils play a variety of roles in the body. They help to destroy germs and foreign organisms as well as playing a role in inflammation, especially during an allergic reaction. Eosinophilia, a condition in which eosinophils are elevated beyond normal levels, can be caused by a variety of conditions. High eosinophils can be the result of a severe allergic reaction, an autoimmune disorder, infection, leukemia and other cancers, lupus, Crohn's disease, ulcerative colitis, or asthma. A low eosinophil count may be caused by conditions that cause excess cortisol production like Cushing's Disease or excessive alcohol ingestion.
An irregular eosinophil count will likely require additional testing to narrow down the cause. Eosinophils are also measured as part of a Complete Blood Count (CBC), a more comprehensive test that measures other types of WBC's as well.
Turnaround for this test is typically 1 business day.
