Food Sensitivity Testing in Rancho Santa Margarita, CA

What is Food Sensitivity Testing?

Food Sensitivity Testing uses advanced lab testing across hormones, gut, mitochondria, and inflammation to identify root drivers of chronic symptoms. It is part of our Functional Medicine pillar — one of three integrated care pathways available to Rancho Santa Margarita patients at FRI.

Who is it for?

Food Sensitivity Testing is most useful for patients with fatigue, hormonal symptoms, autoimmune conditions, gut issues, brain fog, or chronic inflammation that mainstream workups have not resolved. During your initial visit we'll confirm whether this is the right tool for your case or whether a different approach would serve you better.

ZIP 92688 is about 6 miles from the clinic at 26400 La Alameda, Suite 100, Mission Viejo 92691. The closest other cities in this service area are Mission Viejo (92691), Lake Forest (92630), Aliso Viejo (92656).

What happens in the session

Food sensitivity panels measure immune reactions that are not the same as an allergy skin test. A long red list is a hypothesis, not a life sentence.

We cross-check the list with a structured elimination and reintroduction so you only keep avoiding foods that actually change symptoms.
