A normal percentage of eosinophils in the blood is 1% to 4%. This means that 1 to 4 out of every 100 white blood cells should be eosinophils.
Eosinophils are a type of white blood cell that helps fight off parasites and allergic reactions. An increased number of eosinophils can indicate a parasitic infection, an allergic reaction, or certain types of cancer. A decreased number of eosinophils can be caused by conditions such as alcohol abuse or stress.
Normal eosinophil count in absolute terms is usually between 30 and 350 cells per microliter of blood.
However, it's important to note that these are just general ranges, and the specific normal range may vary slightly depending on the laboratory and the individual's age, sex, and other factors. If you have any concerns about your eosinophil count, it's always best to talk to your doctor.
