KANSAS CITY, Mo. — The Community Blood Center says hospitals' supply of Type O blood is dangerously low across Kansas and Missouri.
The CBC stated there was a sharp drop in donations over the July Fourth holiday, with overall collections down 25%.
Currently, the region's supply of O negative and O positive is at a one to two-day supply. Usually, providers want to have enough blood for a seven-day supply.

The center is issuing an urgent call for O negative and O positive blood, two of the most critical blood types for emergency and trauma care.
The center states type O negative is the universal blood type and is used when a patient's blood type is unknown. Type O positive, the most common, is used for surgeries, childbirth, cancer treatments and daily medical care.

Chelsey Smith, CBC public relations director, says CBC often sees a drop in donations during the summer.
CBC gets about 20% of its supply from school blood drives. However, with summer vacations, she says the center is seeing a big drop during a time when it's needed most.
"People are outside. They are doing things that are more likely to cause injuries that may require a blood transfusion," Smith said. "So during a season when we often see a drop in donations, we see a spike in blood usage, and it often creates a blood shortage. And that's what we're facing today."
Blood donors can give every 56 days, and platelet donors can give twice per month.
