  • Predictive test for adverse reactions to iodinated radiographic contrast media
    Patent number: 4717657
    Abstract: To determine whether a patient will react adversely when injected intravenously with an iodine-containing contrast media, a sample of the patient's whole blood, whole blood depleted of red blood cells or plasma is treated to activate complement, and the level of at least one product resulting from complement activation is quantified and compared to the level of that product obtained in patients of known reactivity to radiographic contrast media.
