And many of them are residing in different organs and tissues.

Many of them also move around your entire body.

They patrol and they try to check out different tissues and organs, and then they see what's going on.

It has to remember, have I seen the flu?

Have I seen the COVID?

Or have I seen a lot of inflammatory signals?

So now in my next response, I may want to anticipate what's coming in.

They actually don't have a very good way to summarize overall how's your immune health.

All we got typically, if your doctor orders it, it's what's called a CBC.

It's a complete blood cell count.

That's right.

I'm Canadian.

So the complete blood count, it provides you with the absolute count and frequency of certain cells in your blood.

That's nothing very specific you can basically tell by just looking at those numbers.

But how to link the CBC to the healthy immune system and how to link the CBC to other aspects of your health, it's still an open problem.

In our case, we started with both clinically healthy people, so no obvious disease, and then also various groups of people suffering from various genetic defects.

Each one of these persons is suffering from a natural perturbation, or it's like a hammer knocking stuff around in their system.

If we look at enough of these people where the hammer is knocking on different points in the immune system, we can build a map on how different parts of the immune system, it's connected to each other, number one, right?

And number two, we can start to ask the question, despite that these diseases originated from different parts of the immune system being perturbed, are there common deviations?

And we call that common deviation from health.
