About the GX Sciences Lab:


The GX Sciences Laboratory is a CLIA approved advanced testing facility located Austin, Texas.

GX Sciences chose Thermo Fisher and Life Technologies as its core testing platform and partnership. This partnership has allowed the company scale in areas of genetics, clinical chemistry, and other advanced testing. As the company continues its growth path, its operations focuses on Lean Six Sigma processes throughout all areas of the facility allowing the company to achieve turnaround times of 5 business days for genetic testing results.


Founded by
Kendal Stewart, MD and Kara Stewart-Mullens, this state-of-the-art facility has opened the world of Nutrigenomics and Pharmacogenomics to all types of medical clinicians at an affordable price.


"The goal of the GX Sciences' panels is to scientifically evaluate and nutritionally support the functional uniqueness of each patient in a precision medicine approach. Many physicians can find genetics, biochemistry and even nutritional recommendations quite frustrating. My goal for all providers is to make biochemistry fun again and to simplify and consolidate the ongoing medical knowledge of functional nutrition into an easy-to-use clinical tool that helps each patient and practitioner alike."

- Kendal Stewart, MD / Founder and CSO
