I missed the timing of the morning sample collection (saliva T30, urine): what should I do?
Updated on 12 November 2026
As part of the Complete Panel in France, we measure CAR (Cortisol Awakening Response) using two saliva samples, taken at T0 and T30. It’s essential that the T0 sample is collected right upon waking, without getting out of bed, and that the T30 sample is collected exactly 30 minutes after the first. During this 30-minute window, please don’t drink, eat, or brush your teeth.
If any of these steps couldn’t be respected, please cancel your appointment from your Lucis dashboard (https://app.lucis.life/dashboard/) and let us know. We’ll send you a new kit and help you reschedule your appointment.
