infographic showing the basics of donating blood

Double red cell donation is similar to a whole blood donation, except a special machine is used to allow you to safely donate two units of red blood cells during one donation while returning your plasma, platelets and white cells to you.


A double red donation takes approximately 15 minutes longer than a whole blood donation.

additional red cell apheresis procedures

For donors that would like to give more often and enjoy the apheresis donation experience, we also have  procedures that allow us to collect a single red cells along with platelets and plasma products. This may be important if we have a patient need for other types of products from specific blood types. ImpactLife staff can assist donors in determining the right type of procedure at the right time and location.

Blood Types Needed

Many variables can impact our blood inventories such as weather, holidays or tragic events.  Every day, patients who need blood are in crisis and you can help by volunteering to donate.  Less than 10% of the population gives blood, so donors that give on a regular basis are important to meet these needs. Schedule an appointment today!
