One of these values is absolute eosinophils, which is a type of white blood cell that plays an important role in the immune system. (healthchek.in)
In this blog post, we'll take a closer look at what absolute eosinophils are, what they indicate in a blood test, and what factors can affect their levels. (healthchek.in)
This value is reported as the number of eosinophils per microliter of blood (cells/μL). (healthchek.in)
Eosinophils are larger than most cells and make up less than 5% of all white blood cells in your body. (healthmatters.io)
If your healthcare provider suspects you have a certain condition or disease, they may order the Eos blood test to check eosinophil levels. (healthmatters.io)
