What Is an EOS Test?
An EOS test is a blood test that measures the amount of eosinophils in blood.
Eosinophil levels can be measured through a routinecomplete blood count (CBC)with differential.
The blood differential test measures each key in of white blood cell, including eosinophils.
Eosinophils and the other white blood cells are measured as counts and as percentages.
Why Would I Need an EOS Blood Test?
A routine complete blood count (CBC) test is also often part of an annual physical.
This blood test will measure your eosinophil level as well as other components in your blood.
From there, your blood will be taken to a lab where it is placed on a microscope slide.
A stain is added to the blood to ensure eosinophils are easily detected; they will appear as orange-redgranules.
Is an EOS Blood Test Painful?
You may feel a mild pinch or sting when the needle is inserted and withdrawn from your skin.
Tell your healthcare provider about any medications or supplements you are taking before your test.
Your healthcare provider will review the results and share them with you.
Different laboratories may have different normal reference ranges.
Your healthcare provider can explain your results and provide clarity if you have any questions.
High Eosinophil Levels
An above-normal eosinophil count is known aseosinophilia.
Results can range from slightly high to severely high eosinophil counts.
Low Eosinophil Levels
Eosinophils are normally low in healthy adults.
However, certain health conditions and medications may suppress eosinophil levels.
What Happens After an EOS Test?
Additional diagnostic tests may involve the cooperation of different specialists.
Depending on your situation, these can includehematologists,dermatologists,pulmonologists,gastroenterologists, andneurologists.
Once the diagnosis is made, treatment can be tailored accordingly.
Summary
Eosinophils are specialized white blood cells that help the body fight off infection.
Your healthcare provider may order an EOS blood test to check the number of eosinophils in the bloodstream.
This may be to investigate the cause of certain symptoms, such as diarrhea, fever, or rash.
Treatment for the underlying cause of eosinophilia typically restores eosinophil levels within a normal range.
Frequently Asked Questions
High eosinophil counts are not associated with stress.
In fact, stress may decrease eosinophil levels.
Allergic reactions to certain triggersincluding foodscan increase eosinophil counts.
Avoiding foods that trigger an allergic reaction can help you maintain normal levels of eosinophils in your body.
In the majority of cases, an elevated eosinophil count will lower once the underlying cause is treated.
