Malaria Card (IMAGE) University of Washington Caption This card is part of a system hoping to diagnose malaria far from any laboratory. The red circle at the center contains dehydrated antibodies that can be stored for months without refrigeration. The lines are tiny channels that guide a blood sample through the card, and the blood mixes with various solutions for set periods of time. When the fluids reach the white rectangle, a red spot will appear, and its intensity shows whether the patient is infected.
