Let’s explore “Immunoglobulin M — lab reference”

CD40LG encodes CD40 ligand, which binds CD40 and supports communication needed for effective antibody responses. It is on the X chromosome, which changes how some genetic results must be interpreted. Also called: The ligand that helps acti…

The Purser genetics reference places CHDH in choline metabolism, while the combined SOP asks clinicians to consider CHDH alongside PEMT and FADS findings.

The older Purser genetics reference uses the heading “DAOA (AOC1)” in its gut section.

Encodes a transcription-factor subunit. The uploaded reference used the label GABP1; no specific variant was established there.

This report overview covers interleukin-4, Th2 cells, immunoglobulin E (IgE), and the report’s discussion of allergic and atopic conditions.

PURSER WELLNESSMTHFR & The Never-Ending Sugar Crash Cycle: Why You’re Always Tired & Craving SweetsA conversation with Dr. Purser

MTHFR & The Never-Ending Sugar Crash Cycle: Why You’re Always Tired & Craving Sweets If you have an MTHFR variant (C677T or A1298C), you may constantly battle fatigue, sugar cravings, and energy crashes — even when you’re “doing everything right.” In this video, we break down exactly why this happens: How MTHFR/methylation issues impair ATP (energy) production at the cellular level Why your body desperately reaches for quick glucose The vicious cycle of blood sugar spikes → insulin crashes → more cravings & fat storage The downstream effects on antioxidants, DNA repair, and overall energy How to finally break the cycle: Targeted supplementation that fills methylation “holes” (what we learned from 15–20k intracellular tests) Why our MTHFR Daily multivitamin was specifically formulated for this The power of CMA intracellular testing Intermittent fasting (12–16 hrs) Fasted cardio (even just a brisk walk) High-protein, real-food diet with minimal processed sugars If you’re tired of the sugar rollercoaster and want stable energy, this is for you.

PURSER WELLNESSAutism Answered - Root Cause Solved with #1 Reviewed MD in the USAA conversation with Dr. Purser

Hi, I’m Dr. Dan Purser. For too long, autism has been treated as a mystery with only symptom management. In this episode, I break down what I’ve seen consistently in practice: the real root cause behind many cases on the spectrum. It starts with genetic variants (especially MTHFR and related SNPs) that break the transsulfuration pathway. When kids can’t efficiently convert homocysteine into glutathione, they lose their ability to detox heavy metals and environmental toxins. The result is chronic inflammation, oxidative stress, and developmental challenges. The good news? Once we identify these biochemical and genetic imbalances through proper testing, we can intervene at the root with targeted support — restoring methylation, rebuilding glutathione function, and giving the body what it needs to heal. This isn’t theory. It’s the Purser Method® in action. If you’re a parent searching for real answers instead of just labels, this episode is for you. The root cause has been solved. Now let’s talk solutions.

PURSER WELLNESSRoot Cause Medicine - What is it?A conversation with Dr. Purser

For those who think I’m “alternative” or “on the edge,” let me clarify: I’m a Western-trained physician focused on root causes. I dive into genetics and vitamin deficiencies because they are grounded in science. Using intracellular vitamin panels and the latest research, I identify deficiencies and address them with the right versions of supplements. I love what I do and am here to help! Read my reviews, and thank you for trusting me.

Happy Halloween from me and Denise! 🎃👻 Denise is rocking Snow White while I’m channeling my inner cowboy, but the real magic happens when you book a CMA Consult with me. That’s the ultimate trick-or-treat for your health—no sugar crash, ju
