⸻ NON-DIAGNOSITC FUNCTIONAL TESTING · CANADA
When guessing isn't working anymore
You've tried the elimination diets. You've taken the probiotics.
The bloodwork came back fine. And you still feel like something is off.
Testing gives us something those things can't, real data.
FOR ADHD ADULTS, THIS MATTERS MORE
01
Irregular eating, chronic stress, and a nervous system that runs hot all show up in your gut data.
02
Testing gives us a picture that accounts for how you actually live — not how you're supposed to be living according to a generic protocol.
03
Not everyone needs testing at the start. Part of what I do in an initial call is help you figure out whether it would actually change anything right now.
X Not diagnostic tools
These tests don't diagnose disease or replace your doctor. They give us a detailed picture to work with.
Think patterns, not diagnoses.
$ No markup. Ever.
All testing is ordered directly through the lab. You pay exactly what I pay.
Nothing added on top.
→ Ships to you across Canada
No clinic visit required.
Labs ship directly to you wherever you are.
⸻ GUT HEALTH TESTING
WHAT'S ACTUALLY
HAPPENING
IN YOUR GUT.
MOST COMPREHENSIVE
GI-MAP
If your gut has been a mess for a while and nothing you've tried has actually moved the needle, this is usually where I want to start.
The GI-MAP looks at your gut's actual terrain: bacterial balance, inflammation, immune function, and whether things like H. pylori or parasites are in the mix. It's also how we untangle which symptoms are gut-driven and which ones are being amplified by your nervous system and feeding patterns.
Most people I work with have already cycled through a few diets and a shelf full of supplements. The GI-MAP is how we find out which of those things were actually relevant to your gut, and which ones weren't.
INVESTMENT: $$$
Good Starting Point
Vitract
A solid starting point when you want a clearer picture without going straight into deep-dive testing.
The Vitract looks at digestion, inflammation, and microbiome patterns, giving us useful information about how well your system is actually breaking down and processing food. Particularly useful when you're dealing with bloating, inconsistent digestion, or food sensitivity symptoms that seem to shift with no obvious pattern.
It's not as comprehensive as the GI-MAP, but for a lot of people, it's exactly the right amount of information to get started.
INVESTMENT: $$-$$$
⸻ HORMONE & STRESS TESTING
WHEN YOUR
BODY IS
SAYING OTHERWISE.
When your energy, mood, sleep, or cycle feel unpredictable and basic bloodwork keeps coming back normal, hormones are usually worth a closer look.
Gold standard of hormone testing
DUTCH Hormone TEST
The DUTCH test shows how your body is actually producing and metabolizing hormones like cortisol, estrogen, and progesterone across the day, not just a single point-in-time snapshot.
That distinction matters, because a lot of what shows up as wird-but-tired, burnout, or cycle irregularity doesn't get caught in standard lab ranges.
→ Wired-but-tired patterns that don't show up in standard cortisol tests
→ Burnout and HPA axis dysregulation — what's actually happening with your stress hormones across the day
→ Hormone metabolism pathways — how your body is actually processing estrogen, not just how much you have
→ Cycle irregularity and mood shifts that basic bloodwork hasn't explained
⸻ ADDITIONAL TESTING
WHEN THE
PICTURE
NEEDS MORE.
METABOLIC INSIGHT
OAT
(Organic Acids Test)
Useful when something feels off but nothing has explained it yet.
The OAT looks at metabolic byproducts in urine to give us insight into nutrient gaps, gut imbalances, detox function, and brain chemistry patterns.
It's often the test that starts connecting dots for people who've been told "everything looks fine."
Investment: $$
THYROID FUNCTION
Thyroid Labs
FULL PANEL — TSH, FREE T4, FREE T3 + MARKERS
Standard thyroid panels frequently miss the full picture.
A complete panel gives us a much clearer read on how your thyroid is actually functioning day-to-day, not just whether your numbers technically fall inside a wide reference range.
Worth looking at properly if low energy, hair changes, or weight shifts haven't been fully explained.
Investment: $$
MINERAL & STRESS PATTERNS
HTMA
(Hair Tissue Mineral Analysis)
A longer-view look at stress load and mineral depletion over time.
HTMA uses hair to reflect what your body has actually been doing over the past several months, particularly useful when burnout or chronic fatigue seems connected to long-term depletion rather than one specific thing.
Investment: $
A few things worth knowing before you book
These tests are not diagnostic tools. They don't diagnose disease or replace your doctor. What they do is give us a much more detailed picture of what's happening in your body, so we can work with actual patterns instead of educated guesses.
All testing is ordered directly through the lab and paid separately from my fees. You pay exactly what I pay. No markup, ever.
If we start testing during your first month, results are typically ready by the time we'd be looking at next steps, so you're not waiting around if you decide to keep going.
That said, not everyone needs testing at the start. Some people make real progress without it. For others, it's the thing that finally makes everything else make sense.
Part of what I do in an initial call is help you figure out which situation you're actually in, so you're not spending money on tests that aren't going to change anything for you right now.
If you're wondering whether functional testing is relevant for what you're dealing with, that's exactly what the call is for.
