500+ data points. One clear picture of your health.

What are you testing for?

Every test below fits one of two goals. Knowing which one you're chasing tells you where to start.

Diagnose a problem

Something's wrong and labs look "normal"

You have symptoms without an explanation. These tests find what standard panels are built to miss.

Start with the summit assessment

Optimize a healthy baseline

You feel fine — and want proof, and a plan

You’re not sick, and you want to stay that way. These tests establish a baseline and track what’s actually changing.

Start with the Precision Lab Assessment

Why It Matters

A standard physical checks maybe 20 markers. We check 500+.

Most testing stops at “normal range.” Ours is built to catch what’s trending wrong years before it becomes a diagnosis — and to give athletes and optimizers real numbers to train against.

Summit Assessment

Our most comprehensive workup — 500+ indicators in a single deep-dive session. The usual starting point.

Precision Lab Assessment

Advanced lab panel for patients optimizing a healthy baseline rather than chasing a symptom.

Brain Gauge® Neuro Assessment

Quantifies cognitive function and neurological health with a fast, non-invasive test.

FibroScan® Liver Health Assessment

Ultrasound-based liver imaging that detects fibrosis and fatty liver disease years before symptoms show.

GlycoCheck® Vascular Health Assessment

Measures microvascular health directly — an early window into cardiovascular and metabolic risk.

Continuous Glucose Monitoring

Real-time blood sugar tracking over days or weeks, not a single fasting snapshot.

InBody 270® Body Composition Analysis

Precise breakdown of muscle, fat, and water — well beyond what a scale can tell you.

Multi-Function Cardiogram (MCG)

Detailed cardiac assessment that catches patterns a standard EKG can miss.

PNOĒ VO2 VO2 Max Testing

Gold-standard measurement of cardiorespiratory fitness for athletes and performance optimizers.

 Trustindex verifies that the original source of the review is Google. I love the James Clinic and everyone there! I have learned so much about how to improve my health and not just how to treat my symptoms. They are so real there. They talk to you. They engage on a personal level and really care about my health and wellness. I feel very in control of my healthcare rather than being controlled by the provider or insurance company. I highly recommend this clinic and its providers!!

 Trustindex verifies that the original source of the review is Google. I cannot say enough positive things about Dr James and her entire staff.  We work primarily with Sara Taylor, NP, and she has been nothing short of amazing.  Our whole family, including my two teenage boys, have been with them for over a year now and we are thankful every day that we found them.  One of my teenage sons has ASD, on top of numerous health issues and the attention Sara and the team has given to help him has been life changing!

 Trustindex verifies that the original source of the review is Google. In addition to being incredibly knowledgable, I really appreciate the care Kate takes with her patients. It's very valuable to me that they are functional medicine physicians/NPs at this practice vs those who wear the doctor title without having medical training.

 Trustindex verifies that the original source of the review is Google. NPs Justina Timms and Sarah Taylor are always incredibly well prepared, knowledgeable and take all the time needed to explain labs and test results to me in ways that I can understand. Their professionalism and expertise continue to astound me. They also check in after procedures or explanations with well documented follow up.  In addition, every nurse at the clinic is warm, friendly, personable, knowledgeable and professional to the Nth degree! Theresa, Michelle, Whitney, Lauren, Brenda, Mary and Chelsea all work hard and are extremely timely when completing procedures such as HBOT and MDI treatments. I have nothing but the highest regard for the James Clinic and all who work there including their lead Dr. Mollie James. My gratitude runs deep for their services.
