Who Should Perform a Melatonin Levels Test?
A melatonin test or circadian phase assessment is ideal for individuals who have one or more of the following:
- Chronic sleep disruptions that have lasted for 14 days or longer
- Trouble falling asleep, staying asleep, waking up, or staying awake during the day
- A consistently irregular or non-24 hour sleep-wake cycle
- An interest in starting a melatonin supplement or sleep aid
- Sleep-wake disruptions after starting a new medication or sleep routine
- Inconsistent results with bright light or Cognitive Behavioral Therapy for Insomnia (CBT-I)
Note: While any chronic sleep disruption can impact the circadian rhythm, this assessment is generally not ideal for evaluating non-circadian sleep disorders, such as: sleep apnea, sleepwalking, sleep paralysis, night terrors, nocturnal panic attacks, limb movement disorders, or certain types of seizures and epilepsy.

What Does a Circadian Rhythm Test Measure?
This at-home sleep study measures melatonin to profile your actual circadian rhythm function and timing. Results can be used to evaluate your actual circadian rhythm alignment/length, or determine if there is any disruption to melatonin synthesis, secretion, metabolism, and clearance, resulting in abnormal melatonin levels over time. This information can then be used in tandem with a sleep health professional to uncover potential issues or aid in treatments that can significantly improve your sleep-wake cycle at a biological level. Learn more about melatonin levels testing below.
What Assessment Do I Need?
It is important to know some basic information about your sleep-wake cycle to help select the appropriate assessment. If you were advised to obtain a recommendation from the Biology of Sleep team or are working on your own initiative to better understand your biology, you can take the 5-question Biology of Sleep Survey below for a recommendation or Ask an Expert to request an assessment recommendation directly.
