Blood collection centers in New York are putting out a request for so called universal donors during the summer vacation season.

O Negative blood can be transfused to anyone, even where there is no time for cross-typing.

Officials say, traditionally, supplies tend to dwindle when schools let out for summer and people go on vacation. On the other hand, the demand for transfusions also usually goes up as people are more active and can be prone to more serious accidents and injuries.

To schedule an appointment to donate blood, call 1-800-REDCROSS (1-800-733-2761).
