 Salivary Cortisol test kit (you get from the lab):

It's a saliva test. No need to fast. Once you complete the test return the tubes to the lab as directed.

Times to collect:

1st tube: 8am-10am Saliva collection should be done at the earliest 60 minutes after brushing teeth, a meal (liquid/solid food intake) or oral intake of medication and 10 minutes after rinsing the mouth with water in order to avoid contamination of the saliva by interfering substances.

4th tube: 10pm-1am
