Blood Products

  1. Donor Qualification, Collection, and ReactionsStart here

    Donor screening, collection controls, reaction response, and special donations protect donors and blood recipients.

  2. Blood Product Processing, Storage, Components, and Quality Control

    Whether a collected blood product can be released depends on its testing, labeling, storage, component preparation, and quality control.

Blood Group Systems

  1. Blood Group Foundations and Carbohydrate Systems

    Inheritance, glycosyltransferases, and developmental expression explain the serologic patterns of ABO, H, Lewis, Ii, P1PK, and Globoside antigens.

  2. Rh and Other Blood Group Systems

    Rh, MNS, Kell, Kidd, Duffy, Lutheran, HLA, and platelet antigens shape antibody identification, compatibility, and rare-donor support.

Blood Group Immunology

  1. Blood Group ImmunologyUpdated

    Immune memory, immunoglobulin class, reaction conditions, and complement explain how red-cell antibodies appear in blood-bank testing.

Erythrocyte Physiology

  1. Erythrocyte Physiology and the Storage LesionUpdated

    Refrigerated red-cell storage alters membrane integrity, metabolism, oxygen affinity, hemolysis, and posttransfusion recovery within the quality limits of the approved component system.

Hemolytic Disease of the Fetus and Newborn

  1. Hemolytic Disease of the Fetus and NewbornUpdated

    Maternal IgG antibodies can injure antigen-positive fetal red cells, and antibody identification, fetal surveillance, neonatal testing, transfusion support, and anti-D prophylaxis together form one laboratory pathway.

Immune Hemolytic Anemia

  1. Immune Hemolytic Anemia: Diagnostic Framework and Cold-Reactive Disorders

    Hemolysis findings, direct antiglobulin test patterns, thermal amplitude, and antibody specificity distinguish incidental cold reactivity, cold agglutinin disease, cold agglutinin syndrome, and paroxysmal cold hemoglobinuria.

  2. Warm, Mixed, and Drug-Induced Immune Hemolytic Anemia

    Warm autoantibodies, mixed thermal reactivity, routine-DAT-negative patterns, and drug-associated antibodies require distinct serologic evaluation and coordinated transfusion support.

Transplantation

  1. Transplantation Immunology and Laboratory Support

    Graft type, allorecognition, and the HLA and ABO barriers shape rejection risk, histocompatibility testing, and transfusion support in solid-organ and hematopoietic transplantation.

Serologic and Molecular Testing

  1. Pretransfusion Testing: ABO, Antibody Investigation, and CompatibilityUpdated

    Recipient identification, ABO and D typing, antibody investigation, unit selection, and crossmatch form one continuous compatibility process.

  2. Special Serologic Reagents and Methods

    Antiglobulin reagents, selective cell treatments, molecular methods, and platform controls resolve complex blood-bank reactions while preserving each method's limits.

  3. Leukocyte and Platelet Antigen Testing

    HLA, HNA, and HPA testing separates immune from nonimmune platelet failure and directs compatible component support in selected transfusion investigations.

  4. Blood Bank Quality Assurance

    Blood bank quality assurance keeps testing and component workflows reliable through validation, traceable records, proficiency testing, event investigation, external reporting, and corrective action.

Transfusion Practice

  1. Transfusion Indications and Component TherapyUpdated

    Transfusion decisions pair laboratory values and clinical context with the expected response to each component, special processing requirement, and emergency support plan.

  2. Transfusion Reactions and Transfusion-Transmitted Infections

    Suspected transfusion reactions require an immediate stop, a structured laboratory workup, and defined reporting, while donor testing, pathogen reduction, and look-back limit transfusion-transmitted infection.

  3. Apheresis, Blood Administration, and Patient Blood Management

    Therapeutic apheresis removes pathogenic blood constituents, component administration follows identification and handling safeguards, and patient blood management pairs transfusion with nontransfusion alternatives.
