Making a Difference!

Working at CTS is more than a job, our employees are making a difference!

Our employees know that while working at CTS they are keeping the nation’s blood supply safe, which contributes to the life-saving mission.

CTS is the largest nonprofit blood donor testing laboratory organization in the United States, testing over 8 million blood donor samples, or 70% of the U.S. blood supply each year.

Our laboratories are in Charlotte, Dallas, Phoenix, St Louis, and Tampa. We are owned by three of the leading U.S. blood service providers: American Red Cross, OneBlood, and Vitalant.

We invite you to explore the various “hot” laboratory positions and then review our current openings here.
