Narrative:

En route orf to iad over the hpw VOR at 14000' encountered severe turbulence followed by loss of 300' altitude, then a climb to 400' above cleared at. Aircraft radar was on 40 mi range and no doppler return was present and no precipitation in the direction of flight. Washington control was notified of the severe turbulence. An initial check with the first F/a was that there were no injuries. The first F/a later reported that other two F/as had hit the ceiling and that one was bleeding slightly on the leg. Approach and dispatch were notified to have medical assistance waiting upon arrival at iad. A medical team met the flight at the gate, no priority was requested as initial report did not indicate serious or disabling injuries. Subsequent talk with ATC revealed there was no conflict involved with altitude deviation.
