JOINT BASE LANGLEY-EUSTIS, Va. –
Robert Winfield, Naval Medical Center Portsmouth phlebotomist, documents donated blood at Joint Base Langley-Eustis, Virginia, Nov. 4, 2024. When volunteers donate their blood, it is collected into a machine that oscillates and stops after a certain amount is collected; Winfield measured the collected product to ensure the amount was accurate accordingly to the weight readily displayed on the machine.
