Melatonin is a hormone primarily produced by the pineal gland in the brain. It plays a crucial role in regulating the sleep-wake cycle (circadian rhythm). The melatonin test measures the level of this hormone in the blood or urine. It's often used to assess sleep disorders, jet lag, shift work adjustments, and certain mood disorders. Melatonin levels typically rise in the evening, promoting sleep, and fall in the morning, promoting wakefulness. This test can help diagnose circadian rhythm disorders, insomnia, or other sleep-related issues. It may also be used to monitor melatonin supplement therapy or to investigate certain types of tumors that can produce melatonin.

Acceptable Range:   0 to 50
Ideal for Women:   10-40
Ideal for Men:   10-40
Ideal for Girls:   10-40
Ideal for Boys:   10-40
Test Method: This test can be performed using blood or urine samples. Blood tests are typically more accurate but require precise timing due to melatonin's natural fluctuations throughout the day.

What do readings below 0 pg/mL for Melatonin - MEL mean?

Low melatonin levels may indicate:

  1. Disrupted circadian rhythms
  2. Insomnia or other sleep disorders
  3. Mood disorders like depression
  4. Exposure to excessive light at night
  5. Aging (as melatonin production naturally decreases with age)
  6. Certain medications interfering with melatonin production
  7. Pineal gland dysfunction

Low levels might contribute to difficulty falling asleep, staying asleep, or maintaining a regular sleep schedule. It may also affect mood and cognitive function.

What do readings above 50 pg/mL for Melatonin - MEL mean?

High melatonin levels may indicate:

  1. Overproduction by the pineal gland
  2. Certain tumors (e.g., pineal gland tumors)
  3. Excessive supplementation
  4. Seasonal Affective Disorder (SAD)
  5. Delayed sleep phase syndrome
  6. Some autoimmune disorders
  7. Certain medications or substances increasing melatonin production

High levels might lead to excessive drowsiness, decreased alertness during the day, or disrupted sleep patterns. In rare cases, it could be a sign of a more serious underlying condition requiring further investigation.
