Advanced Lab Testing for Deeper Health Insights

Functional diagnostic testing is one of the most powerful tools in naturopathic medicine. Rather than simply checking whether your numbers fall within a broad “normal” range, functional testing evaluates your labs against optimal ranges — the values associated with truly good health, not just the absence of disease. This distinction can make all the difference in identifying the hidden drivers of fatigue, hormonal imbalance, digestive issues, mood disorders, and more.

At Sacramento Naturopathic Medical Center in Sacramento, CA, Dr. Godby and our team use a wide variety of specialized lab panels to get a complete picture of your health. Our functional testing services include:

Why Functional Testing Is Different

Conventional lab testing is designed to rule out serious disease. Functional testing is designed to optimize health. Dr. Godby uses our proprietary software reporting system — OptimalDX — to evaluate your blood work against optimal ranges, producing a detailed report that reveals patterns and imbalances invisible in standard reports. This allows us to catch emerging problems early and design targeted interventions before they become serious conditions.

When you pair functional testing with the individualized care approach at Sacramento Naturopathic Medical Center, you get answers — not just “your results look fine.” Call (916) 446-2591 to schedule your functional testing consultation today, or visit our New Patients page to get started.

Frequently Asked Questions About Functional Diagnostic Testing

What is functional diagnostic testing?

Functional diagnostic testing is a specialized approach to laboratory medicine that evaluates your health markers against optimal ranges — not just the standard reference ranges used in conventional medicine. This allows naturopathic doctors at Sacramento Naturopathic Medical Center to identify hidden imbalances, nutrient deficiencies, hormonal disruptions, food sensitivities, and other root-cause factors that may be driving your symptoms, even when conventional tests come back “normal.”

What types of functional lab tests does Sacramento Naturopathic Medical Center offer?

We offer a comprehensive menu of functional lab testing including comprehensive blood panels, food allergy and sensitivity testing, salivary hormone testing, neurotransmitter testing, ThyroFlex thyroid assessment, body composition analysis, adrenal stress profiles, cardiovascular profiles, and many other specialized panels. See our Other Functional Medicine Lab Tests page for the full list.

How is functional testing different from standard blood work?

Standard blood tests use reference ranges built from a broad population sample — meaning your results can fall within “normal” even if they’re far from optimal. Functional testing at Sacramento Naturopathic Medical Center evaluates your results against optimal ranges associated with true health and vitality. Dr. Godby uses OptimalDX software to produce detailed, personalized reports that reveal hidden patterns in your blood work.

Do I need to fast before my blood test?

Yes, most of our blood panels require fasting. The Dr. Godby Adult Panel and other comprehensive panels require a 12-hour fast before your blood draw. Specific preparation instructions will be provided when you schedule your testing appointment. Call (916) 446-2591 with any questions about test preparation.

How do I get my functional lab tests done at Sacramento Naturopathic Medical Center?

Call (916) 446-2591 or visit our Appointments page to schedule a consultation with one of our naturopathic doctors. We’ll review your health history and symptoms, recommend the most appropriate testing panels, and discuss your results in full at a follow-up appointment. You can also review our Blood Test Panels & Pricing page for details on our available panels.

Can functional testing help identify food allergies and sensitivities?

Absolutely. Our food allergy testing identifies both IgE (immediate) and IgG (delayed/hidden) food reactions. Hidden food allergies are often missed by conventional medicine and can be a major contributing factor to conditions like chronic fatigue, digestive issues, skin problems, headaches, and weight gain. Many of Dr. Godby’s patients have seen dramatic improvements after identifying and eliminating their trigger foods.

What is ThyroFlex testing and why is it important?

ThyroFlex is a non-invasive, FDA-approved test that measures thyroid function at the cellular level using a simple reflex test — no needles, no blood. Research suggests up to 80% of the U.S. population has some level of thyroid dysfunction, yet standard TSH blood tests often miss subclinical cases. Sacramento Naturopathic Medical Center is the only provider of ThyroFlex in the Sacramento area and has been performing this test since 2009.
