Low Titer O+ Whole Blood (LTOWB) is a complete blood product containing red blood cells, plasma, and platelets. This unique combination ensures that trauma patients get the blood components they need all at once. LTOWB is specially screened to contain low levels of antibodies. This screening makes it safe for transfusion to patients of any blood type.

Trauma patients often lose significant amounts of blood and need whole blood replacement quickly to increase their chances of survival. Administering blood products in the prehospital setting has been proven to:

• Reduce mortality rates
• Improve patient outcomes
• Deliver faster, more effective emergency care

Medical teams have successfully used LTOWB in hospitals for years. Now, this benefit is available from paramedic services, with proven success in locations like San Antonio and Colorado Springs.

We are currently screening all male, type O+ donors for their titer levels, as they typically have lower antibody levels. Eligible donors must meet the following criteria:

• Be a type O+ male donor with low titer screening results.
• Avoid aspirin for 48 hours prior to donation (as it affects platelet function).

Your usual donation process remains the same, and no special enrollment is required. Simply schedule your appointment and donate regularly to help maintain our inventory.

While O negative is the universal donor type, it’s rare, with only 7% of the population eligible to donate. Type O positive is much more common. It comprises 37% of the population. This makes it a readily available and effective alternative for the LTOWB program.

Absolutely! The LTOWB program is just one part of our overall blood supply needs. Your donations, regardless of blood type, are critical to saving lives both inside hospitals and in the community. Increased LTOWB usage means we need even more donors to meet all blood inventory demands.
