Times of Day for 4-Tube Cortisol Test?

[eyeheartny]

What times during the day should I take the saliva samples? I have a kit from Labcorp but theirs is keyed for taking one sample a day, while I want to do 4 samples in one day. I'm not sure when during the day to take each sample.

And it’s best to order this separate from blood labs. Otherwise they won’t take the bloods until your samples are returned.
