More testing doesn't necessarily mean more answers. Greer McGuinness knows this firsthand. In this conversation, she shares why even extensive lab testing can miss foundational issues, how parents can avoid getting caught in cycles of testing and supplements, and why understanding what to address first can make all the difference. The secret this week is… More Testing Is NOT Always Better
Welcome to Episode 329 of Autism Parenting Secrets.
This week, I'm joined by Greer McGuinness, a registered dietitian with nearly 20 years of experience in nutrition and pediatric health.
Greer's work is deeply personal.
When her son experienced developmental regression, severe constipation, feeding difficulties, and sleep problems, conventional lab results weren't providing the answers she needed.
Determined to understand what was happening, she began exploring increasingly sophisticated testing. But she eventually realized that gathering more information wasn't necessarily bringing her closer to the answers she was looking for.
Today, Greer is the founder of Biomedical Healing for Kids, where she specializes in autism, the microbiome, nutrition, and environmental health.
We explore why identifying foundational issues is so important, how gut health and nutrition can influence other systems in the body, and why the order in which parents pursue interventions matters.
Greer also shares why she has moved away from certain commonly ordered tests, what parents should understand about interpreting lab results, and how chasing supplements or jumping into aggressive protocols can sometimes backfire.
Above all, this conversation is about knowing where to focus, making more informed decisions, and ensuring that every step you take has a clear purpose in supporting your child.
