Our bodies are complex systems built to defend us from infections and foreign invaders. Among the many protectors within our immune system are eosinophils, which is a type of white blood cell that plays a quite an important role in responding to parasites, allergens and other harmful organisms. Let us get to know more about eosinophil levels.
What is an eosinophil count?
An eosinophil count is a test that measures the number of eosinophils in a microlitre of your blood. Eosinophil cells are formed in the bone marrow and are usually found in the blood, lungs, skin and gastrointestinal tract.
Doctors may request this test when a patient is showing symptoms such as breathing issues, unexplained skin rashes, stomach pain or chronic fatigue. The count helps determine whether eosinophils are abnormally high or low, which can signal an immune response or a more serious disorder.
What is the normal range of eosinophils?
A normal eosinophil count ranges from 30 to 350 cells per microlitre of blood. A slightly higher or lower result may not be cause for concern, especially if it’s temporary or due to a mild allergy.
However, when levels rise significantly, the condition is called eosinophilia, which can be classified as:
- Mild: 500–1,500 cells/microlitre
- Moderate: 1,500–5,000 cells/microlitre
- Severe: Over 5,000 cells/microlitre
What level of eosinophils indicate cancer?
While eosinophilia is often linked to allergic reactions or parasitic infections, persistently high eosinophil levels may, in rare cases, signal cancer.
Types of cancer associated with high eosinophil counts include:
- Hodgkin lymphoma
- Breast cancer
- Cervical cancer
- Ovarian and prostate cancers
- Colorectal cancer
Your healthcare provider will not rely on eosinophil levels alone to make a cancer diagnosis. They may recommend further investigations such as imaging tests, biopsies or bone marrow analysis.
For families, especially those with ageing members, the cost of multiple diagnostic tests can add up quickly. This is why medical insurance for parents becomes an essential safeguard. With the right plan in place, you can ensure your loved ones receive timely tests, follow-up care and any necessary treatments without financial strain. Regular check-ups, especially after age 50, can help identify abnormal blood results early.
Conclusion
If your eosinophil count is high, consult a doctor immediately for proper diagnosis and treatment. The treatment plan depends on what's causing the high count. The doctor may recommend avoiding things that could increase the count, such as taking medicines to reduce inflammation and fight parasites. The doctor may advise getting chemotherapy or radiation therapy if it is cancer.
If you're concerned about your health and the cost of treatment, it's important to have a good health insurance plan in place. A medical insurance plan can help cover the expenses of your treatment, including doctor visits, tests, and any necessary medications. If you're worried about the costs for your parents, there is specific medical insurance for parents available for them too.
