CSL Laboratories

Putting Your Plasma to the Test

The CSL Plasma Testing Laboratories are located in Knoxville, Tennessee and Göttingen, Germany. Each Laboratory employs a combination of licensed technical, non-technical, and support personnel. The Laboratories test millions of plasma samples each year, ensuring the safety of the plasma. Both serological and Nucleic Acid Testing (NAT) is conducted to identify viruses. NAT testing allows certain viruses to be detected even before a donor displays any symptoms or develops antibodies. This very sensitive screening can detect viruses earlier than serological testing.
