Can I order this test on its own?

Most labs can be ordered on their own with the “Lab Only” option, which includes a general results review. If you’d like your results personally reviewed — with a written Root Cause Report and personalized 12-week protocol — explore the 12-Week Program. Either way, add Tiffeny Parker as your practitioner when you register your kit so I can see your results.

Is this a medical diagnosis?

No. Functional lab testing is educational and is used to guide nutrition, lifestyle, and supplement strategy. It does not diagnose, treat, or cure any disease. Always work with your licensed healthcare provider for medical concerns.

How long do results take?

Most kits are collected at home in a single day and returned by prepaid mail. Results typically take about 2–4 weeks, depending on the panel.

Stress, Sleep & Neurotransmitter Testing

Sleep and Stress Test

Also known as: Urinary cortisol, cortisone & melatonin profile

Cortisol and melatonin — the two hormones that run your sleep-wake cycle.

UrineAt-home collection kit

How to get this lab ↓

Good sleep depends on cortisol rising in the morning and falling at night, while melatonin does the reverse. This urine test measures your stress and sleep hormones together, along with cortisone, to show where your rhythm may be breaking down.

What it measures

Stress Hormones

CortisolYour main stress hormone and internal alarm clock.
CortisoneThe inactive form of cortisol — seen together, they give a fuller picture of total adrenal cortisol output.

Sleep Hormone

MelatoninProduced in response to darkness; signals your body it's time to fall and stay asleep.

Reference Marker

CreatinineUsed to adjust results for how concentrated the urine sample is.

Who this is for

For anyone whose sleep is the main complaint — trouble falling asleep, middle-of-the-night waking, or waking unrefreshed.

Trouble falling asleep
Waking between 1–4 a.m.
Waking unrefreshed
Racing mind at bedtime
Shift work or jet lag

How we interpret it

We read every panel through a functional lens — optimal reference ranges, ratios, and cross-panel patterns. Results become part of your written Root Cause Report and your personalized 12-week protocol.

Magnesium, calcium, and a steady sodium/potassium balance help the nervous system settle at night, so we pair these results with your HTMA to build an evening routine and mineral plan that supports deeper sleep.

Often paired with

Minerals & Metals Test

Cellular mineral status and heavy metal burden — the foundation of the Method.

Adrenal Cortisol Stress Test

Saliva samples across one day that map your stress hormone curve.

Mood & Mind Neurotransmitter Test

The calming and energizing brain chemicals behind mood, focus, motivation, and sleep.
