I’ve had 3 IgE tests in the past 18 months as my medical team tries to figure out my issues. The first one (Nov 2024) was 4 kU/L. The next one was Oct 2025, and was 3. Shortly after that, I started taking Dupixent for eosinophilic asthma. And my IgE was tested a couple of weeks ago, and is now below their measurement threshold (< 2 kU/L).

Is this something that should be investigated at all? Or is it just a “whatever”? There doesn’t seem to be a lot of studies on it that I’ve found.
