If you are O Rh Positive...

How is the need for blood met?

O+ 39% B+ 8.5% O- 7% B- 1.5% A+ 34% AB+ 3.5% A- 6% AB- .5%

The blood provided by this service comes from all volunteer donors. Among the healthy adult population 17 years of age or older, the following distribution of blood types is found:

O Rh Positive

If you are O Rh positive, your blood donation is very special. Your type is the most common, but also the type that is in highest demand.  O Rh positive comes to the rescue of many patients because it can be transfused to patients with other blood types.

O Rh Negative

As an O Rh negative donor, there is a great need for your blood donation. Your type is uncommon -- only 6 percent of the population is O Rh negative. It is the type we need for patients with negative blood types and for emergencies.  O Rh negative patients generally receive blood only from O Rh negative donors. People with every other blood type can safely be transfused with O Rh negative blood in an extreme emergency, before their own blood type can be determined. In addition, O Rh negative is often the preferred blood type when problems arise in the case of newborn infants.

Thank You!

You are an invaluable donor. Won't you help us help others by donating as often as possible... up to six times a year? 

Thank you for sustaining this vital community resource as a volunteer blood donor.
