Zanolife Q&A – Cortisol Salivary Test for Stress
People in Hong Kong are putting more and more focus on their health every day. From enhanced importance placed on employee health, to the increased availability of information on the latest developments in diet, exercise and health monitoring, people feel more empowered than ever to navigate their own health journeys. Advanced screening is a core component of this, with more types of testing being made available to the public, including wellness DNA testing, hormone testing for stress and ever-improving allergy screening.
Greenamics is one such company operating in this space. Established in Hong Kong in 2009 they are specialised in offering food allergy and sensitivity rapid tests, a series of hormone tests as well as heavy metal screening. Zanolife recently spoke to Greenamics about their cortisol test; a hormone test related to stress and the symptoms of stress, including things like difficulty in sleeping, fatigue, depression, loss of hair and food cravings amongst others.
What is the test? Cortisol Salivary Test. In this test saliva is used to analyse the level of cortisol.
What is cortisol? Cortisol is the ‘stress hormone’ which is synthesized by the adrenal glands; the 2 small glands located above the kidneys. Cortisol plays an important role in our response to stress, the fight against infection, maintaining blood pressure, regulating macronutrient metabolism and our immune system. Normally, cortisol is secreted in a regular pattern throughout the day. Any disruption in the pattern can cause body dysfunction.
Where is it from? This is a test from Germany and is now available on Zanolife.hk. Your saliva sample will be sent to the lab in Germany for analysis, which takes about 2-3 weeks. You may book a complimentary consultation with a nutritionist when you receive the report.
How is it conducted? 7 saliva samples at different times throughout the day are required for this test. The test result will tell you the pattern of your cortisol level throughout the day. The first sample is collected before brushing teeth and eating. For example, if your first saliva sampling time is 09:00 (wake up time = n), the following sampling time would be 09:30 (n 1/2 hr), 10:00 (n 1 hr), 11:00 (n 2 hrs), 14:00 (n 5 hrs), 17:00 (n 8 hrs) and 21:00 (n 12 hrs). Do not chew gum on the sample collection day. Also do not drink, eat or smoke 30 minutes before collecting samples, and do not use mouth wash or other mouth cleansers, 30 minutes before each sampling,
Who should get this test? This test is suitable for individuals who are experiencing certain chronic symptoms including the following: fatigue, depression, irregular menstrual periods, hormonal imbalance, loss of hair and food cravings, etc. Especially when many people in Hong Kong cannot sleep at night and find it difficult to wake up in the morning.
Why is this test important? Cortisol is the most important stress hormone in humans. Failure of cortisol release is life threatening, while an increased cortisol secretion is a reaction of your body to permanent stress. Since the cortisol level undergoes physiological fluctuations throughout the day, the measure of the biologically active cortisol level enables a chronological sequence in a day profile. Saliva test allows an accurate result that is recognized by The National Institutes of Health (NIH) and the World Health Organization (WHO).
What does my report tell me? A 13-page report will tell you your pattern of cortisol level throughout the day. Suggestions are provided to help normalize any irregular pattern. If there are any abnormal deviations with the pattern, you may encounter a particular stress-related condition that may interrupt the secretion pattern.
What actions can I take after I get my results? For example if I have high cortisol: are my results actionable? People living in urban locations tend to have a higher cortisol level. Apart from therapy or remedies to help normalize the stress regulation back to physiological status, lifestyle changes can also lower the cortisol level. Sufficient and good quality sleep, working out and other dietary approaches could help normalize the level of cortisol.
