What does CSL Plasma primarily collect?

CSL Plasma primarily collects human plasma, which is the liquid portion of blood that remains after the red blood cells, white blood cells, and platelets have been removed. Plasma is essential because it contains important proteins, antibodies, and nutrients that can be used for various medical treatments.

Plasma collection is different from whole blood donation, where all components of blood are taken together. While red blood cells and platelets are critical components of the blood, they are not the focus of CSL Plasma's operations. The company specializes in the collection of plasma specifically for the development of therapies and products that can help treat various health conditions, making plasma the correct response for this question.
