Johnson City, Tenn. -

The American Red Cross urgently needs donations to ensure an adequate blood supply is available for patients all summer long.

In a press release, the organization says nationwide donations through the Red Cross were down approximately 10 percent in June. They say that resulted in about 50,000 fewer donations than expected. 

The Red Cross says June can be among the most challenging months of the year for blood and platelet donations because regular donors delay giving while they adjust to summer schedules.

High school and college blood drives account for as much as 20 percent of Red Cross donations during the school year.

Donations from those who usually give at these drives drop by more than 80 percent when school is out for the summer.

If you would like to donate blood, call 1-800-RED CROSS (1-800-733-2767) or visit redcrossblood.org to make an appointment or for more information.
