Why Testing Is the Foundation

Without the Right Data, a Protocol Is Guesswork

Every protocol at Functional Medicine of Houston begins with testing. As an alternative medicine practitioner, does not recommend supplements, dietary changes, or natural support approaches before the data exists to support them. Testing panels are selected based on each patient’s specific history and symptom picture — not applied as a blanket panel to every patient.

The result is a protocol grounded in what the patient’s own physiology reveals — not population averages or general wellness guidelines.

Testing Services

Functional Medicine Laboratory Testing Services

Functional Blood Testing

Advanced metabolic, hormonal, and micronutrient blood panels that evaluate markers standard labs routinely overlook. May help identify nutritional deficiencies, inflammatory patterns, and hormonal imbalances that may be contributing to chronic symptoms.

Food Sensitivity Testing

IgG, IgA, and IgG4, C3d panels that assess immune reactivity to specific foods. Food sensitivities may be a contributing factor in digestive distress, skin conditions, brain fog, and inflammatory patterns that may warrant further investigation.

Gastrointestinal Services

Comprehensive stool analysis to evaluate gut microbiome composition, intestinal permeability, and digestive function. May help identify factors that may be contributing to bloating, irregular bowel patterns, and chronic digestive discomfort.

Mold Testing

Mycotoxin blood panels to assess toxic mold exposure. Mold-related patterns are an underrecognized area of investigation for fatigue, cognitive difficulties, and respiratory symptoms that standard workups rarely evaluate.

Adrenal Testing

Hormone panels and HPA axis assessment to evaluate cortisol patterns and adrenal function throughout the day. May help identify contributing factors in chronic fatigue, sleep disruption, and stress intolerance.

Micronutrient Testing

Intracellular micronutrient assessment to explore deficiencies in vitamins, minerals, amino acids, and antioxidants that standard serum panels do not typically measure. Micronutrient gaps may be relevant to a wide range of chronic symptoms.

Lipoprotein Particle Profile

Advanced cardiovascular risk assessment that evaluates lipoprotein particle size and number — a different picture of cardiovascular risk markers than standard cholesterol panels typically provide.

Telomere Testing

Assessment of telomere length as a marker of biological aging and cellular health. Used as a baseline measure for patients exploring long-term longevity and wellness support protocols.

Testing recommendations are made by Dr. Stowe based on individual patient history and symptom presentation. Functional Medicine of Houston does not diagnose, treat, cure, or prevent any disease or medical condition.

 Trustindex verifies that the original source of the review is Google. I have been working with Dr. Stowe for almost 2 years.
My results have been amazing. I sought him out due to an extremely hyperactive thyroid. I was very, very sick. He set me up for quite a few tests and the results came back showing that I had a VERY leaky gut. Leaky gut can lead to many health issues, many of which are debilitating, as mine were. My thyroid numbers are now fine, my leaky gut is all but nonexistent and I feel 1000 times better. I cannot thank Dr. Stowe enough, really. I am extremely pleased with the results. He is very easy to work with. Very knowledgeable and can explain complex things in an easy to understand way. I have learned a lot. I have healed a lot. I am very thankful for his help.

 Trustindex verifies that the original source of the review is Google. I am writing this review because I genuinely feel that people need to think beyond the traditional medication system and listen to their body by getting it correctly analyzes. I happened to found Dr Stowe after a bit of struggle on hyperthyroidism which was detected as graves disease all of a sudden after  just a little less than 2years of my first child's delivery. This was a shock and my TSH was negative less than 0.006. after alot research on internet and being from indian origin I was more interested in alternative medicine or naturopathy  or yoga to help me.   I am thankful that I found Dr.Stowe, he helped me bring my thyroid back to normal in 4-5months. His treatment must be followed he stresses that, they gave me very exceptional support with all my queries on email as due to pandemic I couldn't visit him. The cost of treatment is high, but Dr.Stowe does let you get a super bill for your out of pocket or out of network expense to claim on insurance and also let's u get some tests done at local LabCorp etc, what ever is best and permissible. His appointments are very detailed and he spends time with you writing and guiding each thing.

 Trustindex verifies that the original source of the review is Google. I suffered from frequent migraines for almost 20 years and for the last few years they started getting worse and more frequent.
They were so frequent that my life started changing. I was in the ER several times and I was absent from my job for many days.
I needed to lay down for days and I couldn’t have a normal life.
I was desperate and looking for help in order to have a better quality of life.
I tried the doctors my insurance covered. I tried diets, exercise, natural and homeopathic ways and I didn’t get the results.
I heard about functional medicine a year ago and I started looking for a doctor in Houston.  Happily, I found Dr. Stowe.
I started with the tests and then the treatment.  I saw results immediately. My migraines started going down and my digestion improved. My energy levels increased, and I started having more hope every day.
After I tried so many things, I finally found the correct treatment in order to have a better QUALITY of life, and it doesn’t have a price.

 Trustindex verifies that the original source of the review is Google. Dr. Stowe and the people who work in his office are all very professional and respectful. The cost of treatment is always communicated openly and upfront so there are no surprise bills. I came to Dr. Stowe in March with very severe eczema and thyroid problems. When I followed his treatment protocol, most of my symptoms went away in a month and a half. I still have some ways to go, but I already feel so much better and my quality of life has improved greatly. Dr. Stowe spent a few hours with me during the first appointment to figure out the root of my problems and created a customized plan to get me off of my prescription meds for good. If you have any chronic disorders, I highly recommend giving functional medicine a try.

FAQ

Frequently Asked Questions

Why does functional medicine use different tests than my primary care doctor?

Standard primary care panels are designed to identify acute dysfunction and flag results outside broad population ranges. Functional medicine testing evaluates a wider range of markers and interprets results through a narrower optimal-range lens — exploring patterns that standard panels may not capture.

How are testing panels selected?

Dr. Stowe selects testing panels based on each patient’s specific history, symptoms, and prior diagnostic records. Not every patient receives the same panel. Testing is tailored to what the individual patient’s situation warrants.

Are the tests covered by insurance?

Functional Medicine of Houston operates on a cash-pay basis. Patients are responsible for the cost of consultations and laboratory testing. This allows Dr. Stowe to order the specific tests a patient’s situation warrants without third-party restrictions on coverage.

How are results interpreted?

Results are reviewed by Dr. Stowe and interpreted through an optimal-range framework — not simply flagged as high or low against broad population averages. Dr. Stowe reviews findings with the patient in detail before building a protocol.

Do I need to stop my current medications before testing?

No. Functional Medicine of Houston does not advise patients to discontinue any prescribed medications without first consulting the physician who prescribed them.

How do I get started?

The first step is requesting a consultation through the website or by calling (713) 667-6656. Functional Medicine of Houston is currently accepting new patients across all of Texas.
