The morning before your lab visit, take your first saliva cortisol sample. Take this before eating, drinking, smoking, taking medication, or using oral hygiene products. Refrigerate the saliva sample. The afternoon/evening before your lab visit, between 4-6pm, take your second saliva cortisol sample. Don’t eat, drink, smoke, take medication, or use oral hygiene products 1 hour prior to taking this sample. 10 minutes prior to taking this cortisol sample, rinse your mouth with clean water. Refrigerate the saliva sample. 8 hours before your lab visit, start fasting. No food or drink for 8 hours prior to your lab visit. This includes black coffee. Water is the exception, be sure to stay hydrated.
Go in-person to your lab location BEFORE EATING BREAKFAST (that includes NO coffee/tea) for your fasting (please fast for at least 8 hours) blood draw. Upon arrival, you need only to give your first and last name, as well as date of birth to be located in Quest's system. Bring with you both of your saliva cortisol collection tube samples.
