Good Evening, Hope you are all doing fairly well this evening. I have a question for you all. Any answer would be appreciated. What is ESO in a blood test mean? My ESO blood test came out as 1.4, is this a normal reading? Can you please tell me what the normal ranges would be?
Thank you much. Hope you all have a wonderful evening.

I'm just wondering if you might mean EOS instead of ESO. Is that possible? The Eosinophil (EOS) normal range is 50-350/mm3. It's a hematology test that's used to diagnose various health problems or diseases. However, if it was something serious, I'm sure your doctor would have called you to tell you about it.
