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 Tustin 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.
