UNDATED -- The American Red Cross is making a plea for blood donations as part of Trauma Awareness Month.

Red Cross spokeswoman Sue Thesenga says there are a number of blood drives being held across central Minnesota this month. She says all blood types are welcome, but O-negative is especially important because it's the universal blood type and can be transfused to anybody with any blood type.

Thesenga says many people think when a patient needs a blood transfusion that only one unit is needed, but a major trauma can oftentimes require several units of blood to save a life.

To sign up for a blood drive, you can download the Red Cross Blood Donor app, visit their website at redcrossblood.org, or call 1-800-Red-Cross.
