Miller-Keystone Blood Centers will conduct a Blood Drive at Jennersville Regional Hospital on June 7 from 7 a.m. to noon in Conference Room A. Healthy people over 17 and weighing at least 110 pounds are usually eligible to donate blood every 56 days. A trained professional screens all potential donors since some medical conditions may temporarily defer an individual from donating blood. Community members are encouraged to call the hospital's Department of Human Resources for an appointment at 610-869-1354. Walk-ins also are welcomed. Bring identification and a list of any medications you may be taking.
