  • Immune Hemolytic Anemias
      • Introduction
      • Direct Antiglobulin Test (DAT)
      • Classification of Hemolytic Anemias
  • Alloimmune Hemolytic Anemia
      • Alloimmune Hemolytic Anemia
  • Autoimmune Hemolytic Anemias
      • Autoimmune Hemolytic Anemia (AIHA): Introduction
      • Symptoms of Autoimmune Hemolytic Anemias
      • Testing for Autoantibodies
      • Possible Serological and Laboratory Presentations
      • True or False: A direct antiglobulin test (DAT) is usually negative in cases of autoimmune hemolytic anemia.
    • Cold Autoimmune Hemolytic Anemia
      • Cold Autoimmune Hemolytic Anemia
      • Cold Hemagglutinin Disease (CHD)
      • Paroxysmal Cold Hemoglobinuria (PCH)
      • PCH Donath-Landsteiner Test
      • ABO/Rh Typing in the Presence of Cold Autoantibodies
      • Laboratory Presentations of Cold Autoantibodies - Antibody ID and Detection
      • In paroxysmal cold hemoglobinuria (PCH), the autoantibody specificity is most commonly anti-I.
      • Cold hemagglutinin disease (CHD) is caused by an IgM antibody with a broad thermal range.
    • Warm Autoimmune Hemolytic Anemia
      • Warm Autoimmune Hemolytic Anemia (WAIHA)
      • Serological Characteristics in WAIHA
      • WAIHA Investigation: Serological Findings Following Elution
      • Possible Scenarios When Transfusions are Needed in the Presence of WAIHA
      • Detection and Identification of An Alloantibody in the Presence of a Warm-Reactive Autoantibody
      • Autologous Adsorption (Autoadsorption)
      • Allogeneic Adsorption
      • Transfusion Considerations for WAIHA
      • Treatment of WAIHA
      • In a case of WAIHA , the production of IgG or IgG and complement that sensitizes the red blood cells leads to red blood cell destruction.
      • Which type of adsorption must be done if a patient has been recently transfused?
    • Mixed-Type Autoimmune Hemolytic Anemia
      • Mixed Type Autoimmune Hemolytic Anemia (AIHA)
  • Drug-Induced Hemolytic Anemia
      • Drug-Induced Immune Hemolytic Anemia Introduction
      • Mechanisms
      • Drug Adsorption Mechanism
      • Immune Complex Mechanism
      • Non-Immune Adsorption of Proteins
      • Induction of Autoimmunity
      • Treatment of Drug-Induced Immune Hemolytic Anemia
      • Laboratory Investigation of Drug-Induced Immune Hemolytic Anemia
      • Which mechanism of drug-induced red cell destruction closely mimics the serologic presentation of warm autoimmune hemolytic anemia (WAIHA)?
      • Which mechanism of drug-induced hemolytic anemia involves the formation of drug-antibody combinations that bind non-specifically to RBC membranes and ...
      • Penicillin is one of the medications that may be responsible for the immune-complex mechanism of drug-induced hemolytic anemia.
