Our Story

      Golden West Diagnostics, LLC (GWD) has been in business since 2015. Our parent company, Golden West Biologicals, Inc. has been in business since 1989. Golden West Biologicals, Inc. opened its first manufacturing site that tailors to customer needs in 2004. Filling the void that the in-vitro diagnostic industry was experiencing. In 2015 Golden West Biologicals, Inc. provided three solutions by transferring its manufacturing division to its subsidiary, Golden West Diagnostics, LLC and transferring its distributed products to Golden West BioSolutions, LLC, while maintaining its distribution of therapeutic Human Serum Albumin for excipient use. Roughly 60% of all business for GWD is considered Custom OEM which allows GWD to work with a wide range of products and processes. If there is a need for specific product, with limited options, GWD has provided a solution, time and time again. A solution not only that meets requirements but is also cost effective for GWD and the customer. Golden West Diagnostics, LLC currently manufactures components for further manufacturing and/or research. GWD is ISO 13485:2016 certified.
