Would it [sodium azide] show up in a tox screen?

I don't know. It breaks down to sodium and nitrogen, both unremarkable.

There might be some distinctive metabolite or lasting effect on a protein or something.

Nitrogen was 22. Normal range is 8-20.

Sodium was 137. Normal range is 135-150.

It says the specimens were received on 3-9, over a week after death. Toxicology report printed 3-13. Report of the analysts printed April 9. Signed off on April 20th, the day Michael Cormier died - possibly by Daniel T. Anderson, Supervising Criminalist II.

I wonder if the results would be different, depending on how long before the tests were run. Would a week of delay cause levels to normalize? Or do the “normal ranges” listed account for the age of the sample?
