Eosinophils Percentage – Care to Share?

Hi All,

I've been tracking my personal biomarkers for several years through Wellness FX and the only marker I ever get in the red reference range is % Eosinophils.

I've been told my high result is likely due to my periodic asthma, I'd like to dig into this a little to better understand how much of this is due to asthma, whether there are any long term health impacts to an elevated result, and things I can do (diet or supplements) to counteract the result.

In 2014, I had 9% and it has steadily increased up to 12.6% from last summer. Anything above 5% is said to be 'high risk'.

Any thought or suggestions much appreciated! And if you feel comfortable, please share your results so I have some perspective.

Here's what it is:

About % Eosinophils

Your eosinophil percentage is part of a test called the white blood cell (WBC) differential. This test looks at the five different types of WBCs in the blood and reports the percentage of each type in your blood sample. If the proportion of one cell type to another is different from the normal range, this can be a clue to your doctor that something is wrong. An abnormally high percentage of eosinophils in the blood can suggest a variety of different problems, such as asthma, seasonal allergies, fungal or parasitic infections, or certain types of cancer. If your eosinophil percentage is lower than normal, this could be due to steroid medicines (prescribed for many reasons), an immune system problem, or an acute bacterial infection.

    Hi Warenpeace!

    The absolute eosinophil count (AEC) is the one that counts. Percentage doesn't mean much. How high is yours?

    Warenpeace, it can be super frustrating to figure out that one red flag on medical test results. It sounds like you've spoken with your doctor about your concerns — that's great!

    Could you talk to your doctor again and ask at what point your doctor would be concerned with an eosinophil count that is higher? And why?

    Your question sounds like a great questionto submit to AAFA's free Ask the Allergist™ service.  You can submit your question by filling out this , and a board-certified allergist will reply within a couple of weeks.

    @cynthia – that's a good plan with the Doctor, I'll try that but I like your other idea even better, I'll submit this via the form, thanks for your assistance and suggestion!

    .668 which appears to be much closer to the 'green' reference range of 0-.5, any thoughts?

    That's just mildly elevated. Could be related to your asthma and/or allergies, and I wouldn't worry much about it. Anyway it is a good idea to ask your doctor.

    My disease Churg-Strauss Syndrome is marked by high eosinophils. When first diagnosed in the hospital after a heart attack caused by eosinophils choking my heart, I had extremely high eosinophils in the 90% range and my primary dictor had never made a referral or warned me, only had me on albuterol, singulair (which is actually a meducation being tied to higher incidences of churg-strauss although causation has not been proven), and I eas just on tapers of prednisone over and over again for over 6 months– so I think you are totally in the right to keep track of your eosinophil level and question doctors and medications because if you leave things solely on them– in MY personal experiences at least– they will miss stuff. 

    Now, a rising eosinophil level in the blood in either percents or total is not a good trend… They are allergic blood cells that cause inflammation and damage. I honestly dont know the ranges off the top of my head. I just recently got my eosinophil down to normal range, but I am on a maintenence dose of prednisone AND have inhaled steroids, and also I work really hard to minimize my exposure to allergens in my home. My disease is a rare and severe allergic disease where the eosinophils actually get into my tissues and organs besides my lungs and it is not the only disease involving eosinophils– many allergic disrases involve them– my best doctor was an immunologist I had after being diagnosed because he was very aware of levels, diseases, and new medications involving eosinophils specifically. If your eosinophils get to a certain level you might qualify for a medication like Nucala that works directly on them. I also have heard the nasal spray called flonase helps by working on lowering eosinophils due to things like ragweed allergies that you might have seasonally and can only avoid to a certain extent.

    Shea, I like how you remind us that one important thing to keep an eye on is whether things are trending in the right direction. One lab test is a single "snapshot" in time, but over time, doctors can see trends develop. 

    Another thing to remember: reference ranges aren't carved in stone. Each lab has its own reference ranges, so what is barely out of range on one lab report might not even be flagged on another.

    Thanks for sharing that Shea, I'm glad to hear your levels are much lower now. I'll consider talking to an immunologist and will continue to work on getting this marker down into the 'green' zone of reference range. Thanks all!
