Following a school shooting at Marjory Stoneman Douglas High School in Parkland, Florida, OneBlood says South Florida area hospitals need O negative blood donors.

The Florida blood center says that while immediate blood needs have been met, hospitals need to replenish their O negative blood supply.

OneBlood is asking donors with O negative blood to visit a donor center or the organization's Big Red Bus blood drive to donate blood.  

O negative is the universal blood type used for trauma patients, the organization said in a press release.

Eligible donors include healthy people age 16 and older who weigh at least 110 pounds.  

OneBlood said interested donors can make appointments by visiting oneblood.org.
