We are an 85+ year-old laboratory that offers a diversified line of independent analytical services. Many of our clients have used our services for decades, among them Boeing, Northrop, the States of California, Washington, and Oregon, many cities, U.S. Military bases, and water districts.
Our history has molded us into what we are today – a world class thriving and diversified laboratory providing a variety of analysis, i.e., a family of labs under one roof. Today, our focus of testing is – Environmental Testing, Drug Testing, Nutraceutical Testing, and Product Certification. We have also, over the past decades have tested in additional other fields which varied depending on the changing needs of our clients, government regulators and the public.
Today our service areas are:
Analytical Services or the “Environmental Group” of labs tests for contaminants in the environment. These labs include Microbiology, General Chemistry, Wet Chemistry, Metals, Organics, and Field Services.
Drug Testing tests racing animals’ urine and blood and nutritional supplements to determine if they contain performance-altering drugs. In 2004, we did more of this testing than any other lab in the world.
Product Certification tests products and certifies them. The main thrust of our Product Certification work is analysis of plumbing products to determine if they leach lead or other metals. After rigorous testing to government and regulatory standards products are certified. To view a list of standards Truesdail currently certifies please see our service offerings.
Nutritional Testing tests nutritional supplements for performance altering additives for both human and animal athletes.
In 1930, when Dr. Roger W. Truesdail was a chemistry professor at Pomona College in Claremont, CA, he developed a unique procedure for food processing using yeast. An entrepreneurial college friend persuaded him to start a business to create and market a yeast by-product. So, in 1931 during the depths of the Great Depression, Dr. Truesdail and his partner established what was then named The California Yeast Products Company and is now Truesdail Laboratories, Inc.
The partners set up operations in Pasadena, CA, close to Dr. Truesdail’s home. Shortly afterward, the partner quit, leaving Dr. Truesdail without a yeast business, unemployed as a professor, and in debt while the country was still deeply mired in the Great Depression.
Dr. Truesdail diversified to enable his nascent business to survive. He converted his small, one-man operation into a testing lab and moved the operation to tight quarters in downtown Los Angeles. In the early years Dr. Truesdail frequently had to borrow from his life insurance to meet his three employee payroll. During World War II there were weeks when not one new piece of business came in the door.
Dr. Truesdail referred to his operation as “The Laboratories” since he envisioned that someday there would be several laboratories under one roof performing a variety of independent testing analyses. Through both prosperous and lean years he kept his vision of multiple labs. We now have the Analytical Services Department, a group of labs that test our environment and performs other specialized chemical tests, a Drug Testing Department, and a Product Certification Department. Dr. Truesdail’s vision has become reality.
During our history, Truesdail has provided a wide range of tests. We adapt our testing to the needs of the public and the environment. In the 1970’s and ‘80’s we were renowned for our expert witness testimony and specialized in forensic science. In the 1990’s, mechanical strength and asbestos testing represented a sizable percentage of our business.
Truesdail Laboratories has weathered the Great Depression, the severe shortage of labor during World War II, innumerable changes in the laws governing testing, and the ups-and-downs of our economy in a burgeoning Southern California
Throughout the years Truesdail has made many significant contributions to the laboratory testing industry. A few are:
