The last lab report showed that my eosinophils were 8. The range on the lab report said the range was 0-4. The absolute eosinophils value was 610 and the normal range was 15-500.

I read online that this could be a sign of an infection or could be a sign of roundworms. Yuck! I have not been out of the states and never dig in dirt and I’m not around animals very much. I don’t always believe what I read on the internet. What could be the reason this level is too high and what can I do about it?


Infections such as roundworm usually cause much higher eosinophil levels. The following can cause mild eosinophil elevation:

  • Mild allergies
  • Hay fever
  • Asthma
  • Eczema
  • Drug allergy
  • Gallbladder problems

Lab result ranges are averages, so levels just above or below the reference are not always “abnormal.” Very high levels can be seen in acute myelogenous leukemia, cancer and Churg-Strauss syndrome. If you otherwise feel well without symptoms, your best bet is to have your primary care physician simply repeat the test in a month or so and see your physician sooner if you have any symptoms of allergies or feeling unwell.
