Why the OAT (Organic Acid Test)?

The value of testing and not guessing will be truly transformative for your health and wellness.  All current functional lab kits on the market have limitations and strengths.  The strength of the OAT is that it is about the only kit that tells us about the small intestines where most disease happens.  The OAT also sheds light about the large intestines.  

The Organic Acids Test (OAT) offers an accurate evaluation of intestinal yeast and bacteria.  Abnormal toxic levels of these microorganisms can cause or worsen behavior disorders, hyperactivity, movement disorders, affect energy levels and immune function.  Many people with chronic illnesses and neurological disorders often excrete one or more abnormal organic acids.  The cause of these toxic levels include: oral antibiotic use, high sugar diets, immune deficiencies, and genetic factors.

Toxins And Your Terrain!

Unlike a stool kit, the OAT (organic acid test) also provides toxin and terrain information about:

  • Kingdoms of microbial pathogens in the gut with a non-invasive first morning urine collection
  • Adrenal Hormones (adrenaline, serotonin, dopamine)
  • Malnourishment (amino acids, B vitamins, glutathione, vitamin C, etc)
  • Mold (markers 2, 4, 9)
  • Fungal and Candida overgrowths also known as SIFO (small intestinal fungal overgrowth)
  • SIBO (small intestinal bacterial overgrowth)
  • Neurotoxin burdens (markers 2, 4, 9, 15, 16, 17, 18)
  • Oxalates
  • Fat Burning capacities and mitochondrial function

Which kit does Dr. Grace prefer for analyzing the burden of fungal overgrowths?

On the current functional medicine market, only the OAT (Organic Acid Test) from Great Plains offers the most comprehensive metabolimic testing for the burden of common, silent and insidious fungal overgrowths. There are limitations: we do not know fungal or Candida species and frankly if the diet is ‘clean’, then many species are quiet.

The OAT is what we use on all clients because I have found it very valuable to assess the fungal and mold burden on each case before designing customized gut protocols. There are 9 markers for fungal overgrowths on the OAT: markers 1 to 9 and oxalate markers 19, 20, 21. Oxalates are products from toxic fungal and mold infections. These are silent or even lethal infections due to missing protective flora in the gut, skin, sinus, mouth, throat and vaginal flora.

We design moderate oxalate diets and protocols to strengthen the ability to naturally break down oxalates. The great joy we have is rebuilding the oxalate-degrading flora such as Bifidobacteria longum and Lactobacillus rhamnosus which are frequently missing after antibiotics.

Dr. Grace uses the OAT results to customize protocols

At The Gut Institute, we have 3 tenets we follow for optimizing health and reversing chronic illnesses like bloat, brain fog and fatigue.  What we frequently see is a combination of autoimmunity, silent inflammation and HPAT-dysregulation.

All of it stems from the loss of our sacred gut allies in the gut.  Our microbiome has lost much abundance and diversity.  In order to restore health, we need to restore the microbiome.  To do so, we need the 3Rs. The OAT results fill in which to focus on.

Please note that during the lab review Dr Grace PharmD will not be providing customized gut protocols.  She will review and interpret your labs as it relates to your microbiome health.

For the fastest healing we need the 3 Rs!

  • Root issues -- resolve these as we discover and identify with testing, surveys and tracking metrics (temperatures, mood, morning wood, PMS, pain, stress etc)
  • Re-colonizing terrain -- find the missing keystone species in gut and restore these. The biome is always overrun with pathogens, yeasts, viruses, parasites and co-infections when these protective keystone species are missing. We want to gently weed these pathogens out while using potent and effective probiotics to seed the terrain. Recolonize from tongue-to-toes means comprehensive approaches for the skin, vagina, sinuses and other terrain
  • Reset adrenaline/cortisol/thyroid/anabolic hormone and temperature rhythms

What do clients observe as their OAT results improve?

Improved or resolved chronic inflammatory issues, hormone imbalances and reversal of autoimmunity! See two before and after stories below!

“Thank you for showing me that if I stick with this treatment that REAL healing can happen! I know I have a ways to go still but to have such drastic improvements on where I was in January [10 mos ago] when you and I first started just blows my mind! I was very skeptical in the beginning but you’ve made a believer out of me! Thank you also for taking the time to answer my questions lately and really make me feel secure like I really have a healthier future outlook ahead of me to look forward to! I haven’t gotten that warm and fuzzy and secure feeling from a doctor in a long time! Thank you for being that doctor for me where others haven’t! I can’t tell you how much my family and I appreciate you and the work you do! You’re a true blessing, Grace! - Chris M. Verified Buyer
