Eosinophils
What It Measures
Eosinophils are white blood cells that play a role in allergic reactions and in defence against parasites. This test measures how many eosinophils you have in your blood.
Why It Matters
A raised eosinophil count can indicate an allergy, asthma or a parasitic infection. They therefore give useful information about your immune system.
When to Test
Eosinophils are usually measured within a complete blood count, for example with allergy symptoms, asthma or skin complaints.
Symptoms
Low Levels
A low eosinophil count rarely has consequences and usually causes no symptoms.
High Levels
A raised count is common with allergies, asthma or a parasitic infection.
Lifestyle Tips
If you have allergy or asthma symptoms, avoiding known triggers can help. Discuss persistent symptoms with your doctor.
