Frequently-Asked Questions

1. What is cortisol?​

Cortisol is a steroid secreted in the adrenal gland. It is called a “stress hormone” because it is released in stress. Normally, cortisol is secreted according to a regular pattern throughout the day. Any disruptions in the pattern can cause body dysfunction.

According to many recent researches, free cortisol is present in saliva, but not in serum or urine. Also, salivary cortisol is stable for 7 days. Sample can also be collected under a stress-less condition, thus not affecting the result of the test.

3. How much saliva is needed for the test?

Seven samples of saliva are required for the test and each requires 2-3ml. They are collected at different time throughout the day to trace the secretion pattern for the day.
