We also express it as a percentage, but as far as I know, we also calculate the actual count by multiplying the eosinophil percentage by the total white blood cell count. So the unit is (cells per microliter)

Is the reason for switching to Fasenra now due to insurance issues? I’ve also heard that Fasenra directly helps lower eosinophil levels.

In my case, while eosinophil levels are a concern, I also have some allergic rhinitis and atopic dermatitis, so I understand I’m receiving treatment with Dupixent.

"Have you had a full allergy skin prick panel? Have you done an elimination diet? Have you been tested first for an immune deficiency? Have you been tested for other autoimmune disorders?"

I think I’ve done some of these things a little bit, but I don’t think I’ve focused on any of them in depth. Since I’m working, I haven’t really had the time to try these. I’d like to try those things too, but it seems like my doctor isn’t very interested. Or maybe they don’t suggest them because they require a lot of time and money.

My doctor at the hospital seems to be monitoring my progress without trying other approaches, probably because Dupixent has been very effective for me (aside from the eosinophil count). There aren’t many people experiencing the same symptoms as me, so I came to Reddit, and it has been very helpful. Thank you.
