Serotonin is not just the happiness hormone. Now measure yours.
A lab test you do at home, shipped to your door — serotonin and the messengers around it, interpreted one-to-one by a neuroscientist.
Serotonin Check
- Urine neurotransmitter profile with your serotonin level at the centre, measured by mass spectrometry
- Plus the context that makes it readable: dopamine, noradrenaline, adrenaline, GABA, glutamate
- Kit shipped to your home, prepaid return to the lab
- Results session with Francisco (neuroscientist) included
Serotonin + Stress Panel
- Everything in the Serotonin Check
- Plus your cortisol rhythm: 4 saliva samples across one day — how your stress axis moves from morning to night
- The pairing that answers: low and wired, or low and flat?
- Results session with Francisco included
Both prices include the test kit, lab analysis, shipping within Portugal/EU, and the results session. VAT exempt: clinical psychology service (art. 9(1) of the Portuguese VAT Code). Lab analysis by Doctor’s Data (LC-MS/MS), ordered by MuLabs as registered practitioner via Nordic Laboratories.
A complete collection kit, nothing to figure out
The Nordic Laboratories kit comes with everything: collection tubes, step-by-step instructions, and the prepaid return packaging for the lab. You collect at home, in your own time.

Prepaid envelope to the lab. Analysis takes about 2–3 weeks.
Results, explained
A one-to-one session with Francisco: your numbers, what they mean, what to do next — integrated with your qEEG if you have one.
What the test actually tells you
Balance, not a single number. A serotonin value on its own is unreadable. Next to dopamine, noradrenaline, GABA and glutamate it becomes a pattern — which systems run hot, which run empty.
More than mood. Serotonin is also the raw material your body turns into melatonin at night — the same system touches mood, sleep and appetite.
Your stress rhythm (Panel). Cortisol measured 4× in one day shows whether your stress axis rises and falls when it should — or runs flat, or peaks at night.
And what it is not. This is a body-level snapshot, not a brain scan. The brain’s live activity is what a qEEG shows — the two together are where it gets interesting.
Honest questions, honest answers
Does urine really measure what’s in my brain?
Not directly — nothing outside a hospital does. Urinary neurotransmitters are a peripheral measure: they show how your body produces and breaks down these messengers. That pattern is informative, especially repeated over time and read next to your symptoms and your qEEG. Anyone who tells you a urine test reads your brain is overselling it; anyone who tells you it says nothing is underselling it.
Who is this for?
People who want data behind how they feel: mood that dips through the day, sleep that doesn’t restore, irritability, cravings, stress that never switches off. It’s also a natural next step after a MuLabs qEEG assessment.
Which lab runs it?
Doctor’s Data, a specialist clinical laboratory, using LC-MS/MS (mass spectrometry) with creatinine-corrected results. These tests are practitioner-only — MuLabs orders them for you as a registered practitioner through Nordic Laboratories.
I take supplements or medication — can I still test?
Usually yes — tell us what you take when you order and we’ll tell you what to pause (some supplements) and what never to touch (prescribed medication — never change it for a test). The results session takes everything you take into account.
How long until I know something?
Kit at your door within days; about 2–3 weeks of lab time after your samples arrive; then your results session is booked at your convenience.
This test is for wellness insight and self-knowledge. It is not a medical diagnosis and does not replace your doctor.
