Recognizing and resolving ABO discrepancies.

Area of Science:

• Transfusion Medicine
• Clinical Laboratory Science
• Immunology

Background:

• Accurate ABO blood group determination is critical for safe transfusions.
• ABO typing involves both forward (RBC antigen) and reverse (plasma antibody) testing.
• Discrepancies between forward and reverse typing can lead to transfusion complications.

Purpose of the Study:

• To review common causes of ABO discrepancies in transfusion services.
• To present methods for resolving ABO typing discrepancies.
• To discuss transfusion strategies for patients with ABO discrepancies.

Main Methods:

• Review of literature on ABO discrepancies.
• Analysis of causes and resolution techniques.
• Presentation of case studies illustrating transfusion management.

Main Results:

• Identified various causes of ABO discrepancies, such as weakened antigen expression or unexpected antibodies.
• Outlined resolution pathways, including serological and molecular methods.
• Demonstrated appropriate transfusion choices based on discrepancy type.

Conclusions:

• ABO discrepancies require careful investigation and resolution to ensure patient safety.
• Molecular testing offers a valuable tool for resolving complex ABO discrepancies.
• Effective management of ABO discrepancies is essential in clinical transfusion practice.
