The Autism Urine Test That Detects 90% of Cases | Dr. Christina Flynn, ASU
Biohacking Autism with Nadia Elkhatib.Show Notes
The autism urine test that detects 90% of cases with 100% specificity is here. In this episode of Biohacking Autism, Nadia Elkhatib sits down with Dr. Christina Flynn, the chemical engineer turned PhD researcher who designed the MDM System under Dr. James Adams at Arizona State University. Christina earned her PhD at ASU in December 2025 and now serves as Research Director at Autism Diagnostics Lab. She is also mom to Nico, her 14-year-old nonverbal son. The science she does in the lab is the same science she lives at home, and that lived experience shapes every part of this conversation. Topics covered: what microbially derived metabolites (MDMs) are, why p-cresol may permanently disable a key dopamine enzyme in the brain, why the new ASD-MDM phenotype could finally make autism treatment biological instead of behavioral, where Microbiota Transplant Therapy (MTT) currently sits with the FDA, why home fecal transplants are dangerous, and where families can access the MDM test today through analudos.com. From Dr. Christina Flynn, on the gut microbiome as a garden: Imagine the developing gut microbiome as a beautiful ecological system, an internal garden whose composition exerts profound influence on early neurodevelopment. Under certain conditions, dysbiotic microbial populations, analogous to invasive species, may expand disproportionately, introducing a distinct metabolic signature long before behavioral features become apparent. The MDM System detects these molecular footprints, allowing identification of aberrant metabolic patterns during a critical window of neurodevelopment.

My son was nonverbal. I was told he would never speak, and that if a child does not talk by five, he never will. Jimmy started talking at eight. This is the 11-minute version of my episode on autism recovery: the stories you never hear, what recovery means, how Jimmy started talking, and the five things it takes.
Recovery from autism is possible. I’ve seen it, and my own son isn’t there yet. This is my honest answer after 22 years: the families who got there, why you never hear about them, what recovery means, how my son started talking at eight, and the five things it takes. THE LABS TO START WITH + THE COMMUNITY WAIT LIST https://biohacking-autism.kit.com/d9c8b01fd7 One sign-up. You get the exact baseline panel from this episode in one email, the episode summaries every week, and, if you tick the box, a place on the wait list for the private community. IN THIS EPISODE The recovery stories you never see on social media, and why Two sons, same house, same protocol, one recovered What recovery means and what it does not (the truck analogy) Where Jimmy is today, 22 years in Why there is no one protocol for recovery How Jimmy started talking at eight: Dr. Klinghardt, Babesia and artemisinin The five things it takes, in order Three things to do this week, not five WHAT YOU WILL HEAR Jimmy is not recovered. We have made real progress, and the work continues at 22. Artemisinin was one herb used under Dr. Dietrich Klinghardt’s care alongside pharmaceuticals, for an infection that had been identified. No doses or sources are given, and this is not a recommendation to buy it. The recovery stories are what parents told me directly and what I saw myself. They are not a study.

Caregiver burnout, chronic stress and brain health: the core conversation in a 34-minute Essentials edition for caregivers who want a focused starting point.
Caregiver burnout deserves more than being dismissed as "just stress." When you've spent years caring for someone else, what questions should you be asking about your own brain health?
This is the Essentials edition, a 25-minute cut of our conversation with Dr. Uli K. Chettipally, MD, MPH, an emergency physician, Silicon Valley entrepreneur, and father of Siri, a non-speaking young woman with autism.
