Did you know? 

  • O-negative blood can be transfused to patients of all blood types. It is always in great demand and often in short supply.
  • When O-negative blood is in short supply, specially tested O-positive blood is used in traumas.
  • Patients with traumatic injuries, undergoing cancer treatments or receiving transplants need more platelets than their bodies can produce.

What is a Dual Red Blood Cell donation?

Dual red blood cell is an automated procedure meaning that only red blood cells are removed. Blood is passed through a cell separator which collects the red cells and returns the remaining components to you. Doctors count on concentrated red blood cells for surgeries. Over 60% of blood transfusions are red blood cells. Male donors must weigh at least 130 lbs. and be 5’1” tall; females must weigh at least 150 lbs. and be 5’3” tall.

  • Actual donation time: about 60 - 120 minutes.
  • Dual red cells can be donated approximately every 112 days.

How your donation makes a difference

For 45 years, the South Texas Blood & Tissue Center (STBTC) has been saving lives with the support of donors.

Your donation ensures the blood supply is replenished and ready for patients like Bella, a 2-year-old who is fighting leukemia for the third time.
