Different Mycotoxin Results on Different Labs?

Gotten mycotoxin test results from different labs that don’t line up? This is more normal than you think! It’s confusing, but as a seasoned mold-treating doctor and author of Break the Mold, I assure you it’s completely expected.

I’m here to explain why these differences happen, what each test tells you, and how to use them to fight mold. With the right approach, you can clear the fog and take back your health. Ready to make sense of it all?


Why Different Labs Show Different Results

Mismatching mycotoxin results don’t mean a lab messed up. They’re all testing different things. Each lab’s method targets a unique piece of the mold illness puzzle. Here’s why you see differences:

  • Unique Methods: Labs measure different aspects, like toxin excretion or immune reactions.
  • Test Strengths: Every test has specific benefits and limitations to catch mold-related illness.
  • Your Body’s Input: Your detox capacity and immune response shape what each test reveals.

Understanding Urine vs. Blood Tests

Wondering what these tests actually measure? Urine mycotoxin testing is testing what your body is excreting. And there are differences between the methods different labs use. The blood test is testing what your immune system is freaked out about. Here’s the breakdown:

  • Urine Tests: Detect mycotoxins your body’s flushing out (e.g. Vibrant, RealTime, Mosaic). They show your detox activity.
  • Blood Tests (MyMycoLab Antibody): Identify mycotoxins triggering your immune system to make antibodies, highlighting what’s causing a reaction.
  • Teamwork: These tests complement each other, offering a fuller view of your mold exposure.

Making Sense of Your Test Outcomes

Different results can feel daunting, but you can simply just pay attention to all the positives. Here’s how to interpret your results:

  • Value All Positives: A positive result, whether from urine or blood, signals a mycotoxin that needs attention.
  • No Faulty Labs: Differences reflect the tests’ unique focuses, not lab errors.
  • Tailored Recovery: Your body’s unique response to each mycotoxin shapes your treatment plan.

Smart Testing Tips for Accuracy

Accurate tests are key to your mold recovery, and my Urine Mycotoxin Test Prep handout is a game-changer. Here’s how to test wisely:

  1. Adopt a Low-Mycotoxin Diet: Follow my diet plan for 3 days before urine tests to ensure results reflect your body, not food. Find it at drcrista.com/handouts.
  2. Wait 48 Hours: Allow a 48-hour washout period after your diet change for reliable urine test results.
  3. Skip Glutathione: Avoid glutathione before Mosaic or Vibrant urine tests, as it can lower results.
  4. Stay Hydrated: Dehydration can inflate RealTime lab results, so make sure to drink your normal amount of water.
  5. Assess Immunity: Low IgG or IgE can make blood test results appear falsely normal, so check your immune status.
  6. Choose a Mold-Savvy Doctor: Work with a practitioner trained in mold testing—like doctors who’ve taken my course.
  7. Dive Deeper: Learn testing strategies in my book, Break the Mold and my courses.
