About the GX Sciences Lab:


GX Sciences Laboratory is a high complexity Genetics Testing facility located in the South East Bio Tech area of Austin Texas. Currently, GX Sciences serves over 250 clinicians in over 24 states as well as numerous clients Internationally. Although GX Sciences is leading the field in Nutrigenomics, its test menu consists of other genetic assays centered on personalized medicine.

After reviewing several precision platforms, 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, micro sampling. 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 turn around times of 5 business days for genetic testing results. With the launch of GX Sciences, comes the launch of it proprietary software, SNP Genius, and a customized reporting system. This system allows each provider of various specialties to customize their own genetic panel offering based on their specialty.

Founded by Kendal Stewart, MD and Kara Stewart-Mullens, CEO, this state-of-the-art facility has opened the world of nutrigenomics and pharmaco genomics 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."
