What do you do? What is your investigative pathway or approach? Great.

Yeah.

So I think it starts, I think the two main buckets are how sick is the patient and how severe is the eosinophilia and how persistent is it? Because you can get transient eosinophilia from a drug exposure like DRESS, or they call it DHI these days.

We get a lot of mild eosinophilia.

In Nova Scotia, when I moved here, I noticed that the reference range was less than 0.5 billion per liter.

Whereas when I was a resident in BC, the reference range was up to 1 billion per liter.
