Just like the weather shifts with Winter Storm Fern, our bodies change too.

Symptoms come and go, evolve, and sometimes mask what’s really happening beneath the surface. That’s why getting to the root cause matters.

At Mosaic Diagnostics, this is the work we do every day to help practitioners look deeper for the real healing to begin.

The turning point.
Dakota, 38, came in with extreme fatigue, brain fog, anxiety, dizziness, racing heart, low libido, mood swings, and miscarriage. Every test said “normal,” yet her health kept getting worse.
The MycoTOX Profile from Mosaic Diagnostics revealed the real issue:
💥 Extremely high Mycophenolic Acid
💥 Elevated Ochratoxin A
With this clarity, Dr. Matthew Willis created a targeted plan including mold detox, binders, antifungals, antioxidants, adrenal support, and an anti-inflammatory diet.
The results were life changing:
✅ 100% reduction in Mycophenolic Acid
✅ 75% reduction in Ochratoxin A
✅ Energy, clarity, and mood restored
✅ Anxiety and dizziness resolved
✨ And after 8 years of waiting, Dakota welcomed a healthy baby girl
👉 The right testing changes everything.

New research highlights a critical concern. Aflatoxin exposure may pose greater health risks for immunocompromised individuals, including infants, pregnant women, those with chronic conditions, and the elderly.

A recent review published in Toxins underscores how chronic aflatoxin exposure is linked to immune suppression, liver dysfunction, impaired growth, and increased disease progression in vulnerable populations.

At Mosaic Diagnostics, the MycoTox Profile helps identify aflatoxin M1 along with 10 other common mycotoxins, offering actionable insight into environmental exposures that may be impacting health.

Early identification supports more informed clinical decisions and proactive care.

Symptoms don’t always start where you expect.

IgG food sensitivities can trigger delayed immune responses that affect multiple systems including digestion, skin, mood, and overall inflammation. Because reactions aren’t always immediate, food related triggers are often overlooked.

The IgG Food MAP with Candida and Yeast helps identify immune responses to a wide range of foods, offering valuable insight to support more personalized care decisions.

Explore our IgG Food MAP to learn how targeted testing can help connect the dots.

At 66 years old, Donna was struggling with insomnia, depression, and digestive symptoms that left her feeling unlike herself. Daily challenges such as poor sleep, bloating, and stomach discomfort were taking a toll on her quality of life.

🧪 Working with Ann-Marie Barter, DC, Donna completed MosaicDX testing, including the Organic Acids Test (OAT). The results revealed several key findings:
• Candida overgrowth
• Clostridia overgrowth
• Mold exposure
• Neurotransmitter imbalance
• Oxalate burden and low glutathione
• Nutrient deficiencies

With this clarity, Dr. Barter developed a targeted plan focused on improving sleep, supporting detoxification, restoring gut balance, and simplifying supplementation.

🌱 Over time, Donna experienced a remarkable transformation. Her symptoms resolved, her energy returned, and she was able to resume daily activities she loves, including hiking, lifting weights, and spending time with her grandchildren.

👉 The right testing helps uncover what is happening beneath the surface and guides more effective, personalized care.

✨ Learn how our Enhanced OAT Report delivers clearer insights and more intuitive interpretation for providers.
