What sort of "lab"? I've recently created a home manufacturing "lab" in my apartment due to Covid-19. I'm cooking up electrodes (EEG), soldering PCBs, silicone enclosures, 3D printing and sewing.

I'd like to be testing cortisol, GH, and a few other things but don't think that's possible in a home lab. Let me know if I'm wrong.

Not a native English speaker so... what does it mean "cooking up" EEG electrodes?

I presume it means building, "cooking up" is a slang and its meaning varies, it can mean literally cooking, or also processing an idea, or building something. It relates to creation.

Somewhat dual meaning, yes it means "building", but we also have to cook them in an oven to cure the materials, so also....literal cooking.
