Functional Lab Testing and Advanced Diagnostics
The reason patients stop hearing “everything looks normal.”
Different Question, Different Testing
Standard panels are designed to detect disease. Functional testing asks a different question: what is limiting function right now, and why.
That means more markers, tighter interpretation, and reading results as a pattern rather than one value at a time. It also means re-reading the labs you already have, which frequently contain useful information nobody explained to you.
Testing is selected by hypothesis. Panels are ordered because they will change the plan, not to be thorough for its own sake. You are informed in advance about laboratory costs.
What We Commonly Assess
In-Office Assessment Tools
ALFATHERMO Whole Body Thermography
Non-invasive imaging used to detect patterns of inflammation, circulatory irregularity and physiological stress.
HeartQuest Cardiovascular Assessment
Heart rate variability, autonomic nervous system balance and stress response patterns, used to guide protocols and monitor progress objectively.
ONDAMED Biofeedback
Frequency-based assessment used to identify areas of imbalance and guide individualized support.
Standard panels are designed to detect disease. Functional testing asks a different question: what is limiting function right now, and why.
In Their Own Words
Both of these patients had been tested before. What changed was what was tested for: an infection in one case, a B12 and vitamin D deficiency in the other.
“I came to Dr. Goldstein after suffering from an eye condition that western medicine could not identify or treat. I went to numerous ophthalmologists, was sent to UCI, and had an eye biopsy. Allergy testing, the works. No results after nearly two years. I went to Dr. Goldstein and very quickly she determined I had a deficiency in vitamin B12 and D. She treated me and within a week, my symptoms disappeared and I have been well for three months now. I am forever indebted to Dr. Goldstein and will recommend her to anyone with an undiagnosed or diagnosed problem for treatment and final remedy. I would give her more than five stars if I could. She was the light at the end of my tunnel.”

These are real patients sharing their own experiences, published with their permission. Individual results vary depending on your condition, your history and how long it has been present. Nothing here is a promise of a particular outcome, and this page is educational rather than medical advice.
Frequently Asked Questions
Yes, and we usually do. Prior results are reviewed through a functional lens before new testing is ordered.
Coverage varies. Some conventional panels may be partially covered; many specialty tests are not. Costs are discussed in advance.
No. Testing is selected based on your history and presentation. More testing is not better testing.
Yes. Blood draws are arranged locally and specialty kits are shipped to you. In-office assessments require a visit to San Juan Capistrano.
