Functional Lab Testing in Tustin, CA
Functional lab testing in Tustin — advanced diagnostics to uncover hidden drivers of chronic symptoms. FRI is just 12 miles from Tustin — about a 20–35 minutes drive for most Tustin patients.
What is Functional Lab Testing?
Functional Lab 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?
Functional Lab 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.
What Functional Lab Testing pairs well with
We rarely use any single technique in isolation. For Tustin patients, Functional Lab Testing is often combined with:
- DUTCH Hormone Testing
- GI-MAP Stool Testing
- Thyroid Panel
- Advanced Bloodwork
