TAKE OUR FREE ACNE ROOT CAUSE QUIZ

Functional Medicine

Functional medicine is a type of integrative medicine that focuses on bringing balance back to all body systems rather than treating each individual symptom separately. It uses functional diagnostic lab testing to discover your hidden root causes. This is exactly what we do here at Holistico as it results in a much more efficient path to clear skin!  

Test For Your Root Causes

Katie uses functional testing with her 1:1 clients when it can help guide their individual plan. Options include Hair Tissue Mineral Analysis, DUTCH Complete Hormone Test, GI MAP Stool Test, Cellular Micronutrient Assay and more.

a DUTCH complete hormone test

DUTCH Complete Hormone Test

This is a comprehensive dried urine hormone test measuring sex and adrenal hormones along with their metabolites.

Read full test details

This is a comprehensive dried urine hormone test measuring sex and adrenal hormones along with their metabolites. This test is especially useful if you suffer from PMS, period cramps, irregular or heavy periods, infertility and/or jawline acne. The DUTCH test is a great evaluation if you have or suspect PCOS as it not only looks at the aromatase pathway but also gives complete insight into cortisol, cortisone, estradiol, estrone, estriol, progesterone, testosterone, DHEA and DHEA-S. It also looks at DHEA and progesterone metabolites to evaluate how these hormones are being broken down. We are even able to see cortisol and cortisone pattern to analyze circadian rhythm. Most importantly, it tests your estrogen metabolism pathways to see how well you metabolize estrogen through your liver. This is key for estrogen dominant women as it helps us decipher if phase 1 or phase 2 detoxification is slow and in need of repair. Both of these detoxification pathways can cause acne if under-active. In addition, it measures your daily free cortisol pattern, melatonin (6-OHMS), 8-OHdG and the following organic acids: 

Homovanillate (HVA) – the primary dopamine metabolite 

Vanilmandelate (VMA) – the primary norepinephrine and epinephrine metabolite

Methylmalonate (MMA) – elevated if patients are vitamin B12 deficient 

Xanthurenate – elevated if patients are vitamin B6 deficient 

Kynurenate – elevated if patients are vitamin B6 deficient 

Pyroglutamate – elevated if patients are glutathione deficient

Indican- elevated if patients have gut putrefaction or dysbiosis

b-Hydroxyisovalerate- elevated if patients are biotin deficient

Quinolinate- marker for neuroinflammation

A hair tissue mineral analysis test

Hair Tissue Mineral Analysis Test

This is a non-invasive hair mineral test that evaluates how your body responds to stress and how resilient you are.

Read full test details

This is a non-invasive hair mineral test that evaluates how your body responds to stress and how resilient you are. It gives insight into nutritional deficiencies, gut infections, sex hormone balance, blood sugar, adrenal health, thyroid & metabolic health as well as nervous system balance. It also is an assessment for copper and iron overload. With everyone dieting and taking an array of supplements or pharmaceuticals now a days, mineral imbalances have become extremely common. This is unfortunate because minerals are the backbone to our health and the spark plugs of our body. It is impossible to clear acne if you do not have balanced minerals because you will never be able to detoxify properly. The HTMA test is the best bang for your buck as it is relatively affordable and explains the "why" behind acne, hormone and digestive issues. It displays macro and micro minerals, toxic metal levels and how well your body is able to excrete toxic metals. Minerals are essential but you don’t want too many or too little. It's all about the ratios and overall balance in the body. This is a non-invasive hair tissue mineral biopsy that tests levels of the following minerals and toxic metals: 

Calcium              Nickel

Magnesium      Cobalt

Sodium               Molybdenum

Potassium          Lithium 

Iron                     Boron

Copper               Lead

Manganese      Mercury

Zinc                   Cadmium

Chromium        Arsenic 

Selenium          Aluminum 

Phosphorus

a GI map stool gut health test

GI Map Gut Health Test

This is the most advanced DNA based stool test that gives complete insight into digestion, your gut microbiome and gastrointestinal function.

Read full test details

This is the most advanced DNA based stool test that gives complete insight into digestion, your gut microbiome and gastrointestinal function. This is an important test to do if you suffer from acne, eczema, psoriasis and/or chronic digestive issues like bloating/gas, acid reflux, constipation/diarrhea etc. All disease begins in the gut! The GI Map is the only accurate test for microbes and microbial imbalances that cause acne. After all, gut health and acne are highly connected due to the gut skin axis. This test also provides markers for insight into blood sugar, bile flow, adrenal health, gluten sensitivity, inflammation, immunity, pancreatic enzyme sufficiency, liver function, leaky gut, SIBO, occult blood and antibiotic resistant genes. It also checks for the following bacteria, parasites/pathogens, worms, viruses and fungi/yeast:

Enterotoxigenic Escherichia coli

Enteroinvasive Escherichia coli / Shigella

Escherichia coli O157

Enterohemorrhagic Escherichia coli

Clostridioides difficile Toxin A and B

Cell Science Systems Cellular Micronutrient Assay test kit

Cellular Micronutrient Assay

This is a functional blood test that evaluates your micronutrient status inside your actual cells, not just what is floating around in your bloodstream.

Read full test details

This is a functional blood test that evaluates your micronutrient status inside your actual cells, not just what is floating around in your bloodstream. Standard blood work measures serum levels, which fluctuate day to day and do not show whether your cells can actually use those nutrients. This test measures your white blood cells directly and reflects four to six months of nutritional status, so it catches functional insufficiencies: nutrients you are not absorbing, not activating, or burning through faster than you can replace them. It gives insight into immune function, energy production, detox and antioxidant capacity, gut health, hormone balance, blood sugar, and nervous system health. It is impossible to clear your skin if your cells are missing the raw materials needed to detoxify properly. Instead of guessing with an array of supplements, this test shows you exactly which nutrients your cells are asking for.

Results come back as sufficient, borderline, or insufficient for each of the following 55 nutrients:

Vitamins: Vitamin A, B1, B2, B3, B5 (pantothenic acid), B6, B9 (folate), B12, C, D, K1, K2 (MK4), K2 (MK7), biotin, delta tocotrienol (Vitamin E)

Minerals: Boron, calcium, chromium, copper, iodine, iron, lithium, magnesium, manganese, molybdenum, selenium, strontium, vanadium, zinc

Amino acids: Arginine, asparagine, cysteine, glycine, histidine, isoleucine, leucine, L-glutamine, L-serine, L-tyrosine, lysine, methionine, phenylalanine, taurine, threonine, tryptophan, valine

Antioxidants and other nutrients: Carnitine, choline, coenzyme Q10, glutathione, inositol, lipoic acid, omega 3 DHA, omega 3 EPA, omega 9

Should I order a test before my first session?

Please speak with Katie first if you are considering testing as part of your individual plan. She reviews your history and goals before recommending tests. The Order Inside 1:1 Membership links open the membership page, where you can arrange a call and discuss which tests, collection requirements and laboratory costs fit your plan.

Can clients outside Canada discuss testing?

Holistico works with clients worldwide. Let Katie know where you live when discussing your plan. Laboratory shipping, sample collection and test availability depend on the test and your location, so confirm the practical arrangements and any additional costs with Katie before ordering.

Are testing costs included in the membership?

Membership and laboratory testing are discussed separately. Katie explains which tests she recommends and their current costs before you decide. Ask for the total relevant to your location, including any collection or shipping charges. Do not assume that every test shown here is included in a membership payment.

How does functional nutrition fit alongside medical care?

Functional nutrition support considers food, lifestyle and relevant test results as part of an individual plan. It complements care from your licensed healthcare team. A nutrition consultation or functional test does not replace diagnosis, prescribed treatment or urgent care. Discuss new or persistent symptoms with an appropriate clinician and review any proposed testing or supplements with them.
