Blood is a specialized bodily fluid that contains red blood cells, white blood cells, plasma, and platelets. It is essential for transporting nutrients, oxygen, and waste as well as fighting infection and regulating body temperature.

Whole human peripheral blood is collected in Streck tubes. Streck tubes allow for efficient and easy processing of whole blood in smaller volumes as compared to whole blood bags.

Blood was obtained using Institutional Review Board (IRB) approved consent forms and protocols.
