The American Red Cross has issued an “emergency call” for blood and platelet donations in the midst of what it describes as a continued struggle to find new donors.

Exacerbating the problem was a drop in blood drives during the week of July 4, when about 17,000 fewer donations were collected than needed, according to a news release from the organization Tuesday morning.

“Medical emergencies and critical treatments don’t stop for holiday celebrations. Patients depend on lifesaving blood transfusions every day,” Cliff Numark, senior vice president of Red Cross Blood Services, said in the release. “Right now, the Red Cross only has less than a three-day supply when we need a five-day supply to be prepared for all situations that require blood products.”

As of Tuesday, the national supply of type O blood was less than two days, the release notes.

In June, the Red Cross urged people to donate blood or platelets through a campaign that generated an “encouraging response” but still left the organization with more than 24,000 fewer donations that month than necessary and nearly 700 fewer in northern New England, according to the release.

“Blood is only available when generous blood and platelet donors roll up a sleeve to give, and right now, all donors — especially those (who) have never given or haven’t given in a while — are urged to make an appointment to give today,” Numark said.
