Department
Methodology
Sample Required
Preparation
* Light Exposure: Minimize light exposure (especially blue light from electronic devices) for several hours before and during nighttime collections to avoid suppressing melatonin production. Maintain darkness or dim lighting.
* Fasting is NOT required.
* Medications: Inform your doctor about all prescription and over-the-counter medications and supplements you are taking, especially any melatonin supplements. Do not discontinue any medication without consulting your doctor.
* Avoid Alcohol and Caffeine: Often advised to avoid these for at least 24 hours prior to testing as they can interfere with sleep and melatonin rhythm.
* Stress Reduction: Try to minimize stress before and during collection, as stress can affect hormone levels.
* Sample Collection: Standard venipuncture. Emphasize to the phlebotomist that the sample needs to be immediately protected from light, spun down quickly, and serum frozen.

Frequently Asked Questions
Is fasting required for melatonin test?
No, fasting is not required. However, sample timing is critical as melatonin follows a strong diurnal rhythm.
When should the blood sample be collected?
For accurate circadian assessment, samples are typically drawn in the evening (around 9-11 PM) when melatonin peaks, or as directed by your clinician.
How long does it take to get results?
Results are available within 24-48 hours after sample receipt at our NABL-accredited lab in Chhatrapati Sambhajinagar.
What affects melatonin levels?
Age, light exposure, shift work, beta-blockers, NSAIDs, and certain sleep disorders can significantly alter serum melatonin concentrations.
Can stress impact melatonin results?
Yes, chronic stress and anxiety can disrupt the pineal gland's melatonin secretion pattern, leading to lower or mis-timed levels.
