Our Story 


Pantex was established in 1972 to meet the critical needs of physicians, researchers, and laboratories in detecting and measuring picogram quantities of specific circulating hormones relevant to health and disease.


In 1976, we were joined by Dr. Guy E. Abraham, a pioneering figure in anti-steroid antibody production and early Radioimmunoassay (RIA) development for steroid hormones. This collaboration facilitated Pantex’s production of an extensive range of Iodinated Steroid Kits and Steroid Antisera, setting a standard of excellence in the industry.


Dr. Romulo Garza partnered with us in 1995 in a joint venture to produce anti-steroid antibodies. Renowned as the founder of Radioassay Systems Laboratories, Inc., the diagnostic division of ICN (now MP Biomedicals), Dr. Garza brought his extensive expertise to enhance our capabilities and solidify our position as leaders in hormone detection solutions.


Dr. Garza assumed ownership of Pantex in 2003. As a long-time member of scientific societies including the Endocrine Society and the American Thyroid Association, Dr. Garza kept current with the latest in hormone research and diagnostics. His contributions have been instrumental in our commitment to delivering cutting-edge solutions.


As we continue to evolve and innovate, we honor Dr. Garza and his contributions to the field and Pantex. Pantex remains dedicated to providing high-quality hormone detection solutions and continuing its legacy of scientific excellence. We look forward to the future of hormone analysis and making a lasting impact on the industry. Join us on this journey of discovery and advancement.
