What Does Each Component Measure?

Eosinophils and basophils are types of white blood cells that play roles in fighting parasites, allergies, and chronic inflammation. Elevated levels may signal conditions like asthma, allergies, or certain infections.

IgE Levels: The Allergy Marker

Total IgE measures your body’s immune response to allergens or infections. High IgE levels often indicate allergies, parasitic infections, or autoimmune disorders.

Why Might This Test Be Ordered?

Your doctor may recommend this test if you have symptoms like persistent itching, skin rashes, asthma, or unexplained fatigue. It can also help diagnose conditions like eosinophilic esophagitis or allergic reactions.

What to Expect Before the Test

No special preparation is needed. You’ll have a small needle inserted into your arm to draw blood. If you’re nervous, let your healthcare provider know—they can help make it more comfortable.
