The Community Blood Center of the Ozarks is asking for blood donations of type-O blood as reserves approach critical shortage levels.

CBCO says it has an urgent appeal for type O blood. A strong donor response is needed immediately to avoid a blood shortage of this type.

Current reserves of type O positive and O negative are at critical levels. Less than a one-day reserve is on hand. CBCO strives to maintain at least a three-day supply of blood to be ready for any emergency.

“While it’s not uncommon to have blood shortages of O negative blood, a shortage of O positive is pretty unusual,” CBCO Media Relations Representative Chris Pilgrim said.

“While O negative is the universal type that can be used in any situation, O positive is the most common blood type. Around 38 percent of the American population has O positive blood. As you can imagine, the usage levels of this type mirror the population. It is vital for all type O blood donors to respond immediately to this appeal.”

There are four CBCO Donor Centers in the Ozarks, along with mobile blood drives that take place in various towns within the CBCO service area. CBCO Donor Centers include:

Springfield – 220 W. Plainview Rd. Open Monday thru Friday 8 am to 6 pm. Open Saturday 7 am to 1 pm. Open Sunday 9 am to 3 pm.
