Speakers: Dr Sudha Ranganathan, Consultant & HEAD - Transfusion Medicine Apollo Hospital, Hyderabad- India 

Objective: This article discusses Platelet Crossmatch, an essential method for platelet compatibility in refractory patients. The technique is used to identify compatible platelets in alloimmunized patients. The method is based on the solid phase (Capture-P®), which detects IgG antibodies against platelets. It highlights the importance of standardized methods to improve the management of refractory patients and optimize clinical results. Speaker: Cristina Altobeli de Brito

Objective: To address RhD variants and the importance of their serological detection to guide molecular investigations. It explains how mutations such as SNPs, deletions and gene conversions result in variants such as partial D, weak D and Del. These alterations can cause differences in epitope expression and antisera reactivity. It includes examples of discrepancies in RhD typing and molecular characterization, such as a donor with a CDe haplotype and a patient with myelodysplastic syndrome. The importance of standardized methods and knowledge of variants for safe transfusion practices and accurate diagnoses is reinforced. Speaker: Dr. Tatiane de Paula Vendrame

Objective: A study of RhCE variants is presented, covering detection, classification and clinical significance. RhCE variants are detailed as variant proteins due to genetic polymorphisms, which can affect the expression of RhCE antigens such as C, c, E and e. Weakened expression, partial antigens and the absence of high-frequency antigens are mentioned. The need for greater knowledge of these variants to improve transfusions and blood compatibility in chronically transfused patients is emphasized. Speaker: Dr. Carine Prisco Arnoni

Objective: Platelet refractoriness is addressed, emphasizing its definitions, causes and management strategies. Examples of diagnosis, identification of compatible donors and clinical outcomes of refractory patients are illustrated. Speaker: Juliana Pires Marafon Franz, MD, PhD

Objectives: The implementation of the Type and Screen (TAS) protocol in the blood bank of an emergency center in Lima, Peru, is analyzed, highlighting its usefulness for detecting irregular antibodies (Ac) in safe transfusions. The main points are: The Type and Screen Protocol is a method that combines blood typing (ABO/RhD) with irregular antibody screening to predict compatibility before transfusion in a prospective study between 2016 and 2022, where several types of antibodies were detected, the most common being Anti-E, Anti-Dia and autoantibodies. Solid-phase Capture (Immucor) technology was key to identifying these antibodies. Lissette Fernandez

Objective: To review genomic concepts of erythrocyte antigens. The use of immunohematology when patients have been recently transfused, when patients have some antibody to a high or low frequency antigen but no commercial antibody is available, for the management of patients receiving monoclonal therapies, and in prenatal testing to predict hemolytic disease of the newborn.
