Measure vital hormones to help plan for a better night’s sleep

This at-home lab test measures daily fluctuations of 3 hormones that can help you determine if abnormal fluctuations in the levels of these hormones may be affecting your ability to get a restful night’s sleep.

This at-home lab test measures 3 hormones that play a part in your body’s stress response and sleep-wake cycle.

Your test results will tell whether or not the levels of these 3 hormones are low, normal, or high at 4 defined points in your day. Abnormal fluctuations (elevations or deficiencies at certain times) in any of these markers can point to lifestyle improvements you can make to help improve your sleep and stress levels.

 

Cortisol

Cortisol is produced in the adrenal glands and is released in response to stressors like illness and exercise. Cortisol is often referred to as your body’s “stress hormone,” but it has many roles in the body, including helping to control blood sugar levels and regulating energy metabolism. In most people, cortisol levels peak in the morning and are lowest in the middle of the night. Your sample is collected 4 times throughout the day, and your results will reflect your cortisol levels during those times.

 

Cortisone

Cortisone is a steroid hormone synthesized in the adrenal glands. In the body, it can be converted to and from cortisol. Both serve similar functions, and their patterns throughout the day should be similar.

 

Melatonin

Melatonin is a key hormone of our sleep-wake cycle or circadian rhythm. It is produced in response to darkness and can be suppressed by light exposure. Melatonin works inversely with cortisol as part of the body’s circadian rhythm (the “dark” or “sleep” hormone in the “light-dark” or “sleep-wake” cycle). Melatonin level usually reaches its peak at about 2 to 3 A.M. In addition to a circadian rhythm, melatonin often follows a seasonal pattern with higher levels in the autumn and winter when the nights are longer and lower levels in the spring and summer when nights are shorter.

 

Creatinine

Creatinine is a byproduct of muscle metabolism that gets excreted in the urine via the kidneys. This process is typically tightly regulated, making extremely low or high creatinine rare in individuals with normal kidney function. Urinary creatinine is used as a control to make sure that other markers being tested are not reported inaccurately from kidney filtration problems.
