This test contains a single morning saliva cortisol test.
Cortisol levels are generally high in the morning as we wake from a prolonged period of sleep, with an increase of up to 50% in the first half an hour after waking. This is known as the ‘cortisol awakening response’.
Your test kit and all instructions are posted directly to you, and there is no need to visit a collection centre.
Provide a saliva sample before 10am in the morning.
