Understand the Problem
The question asks for a detailed analysis of a common ABO typing discrepancy, including identifying the probable ABO group, the type of discrepancy, probable causes, and the resolution. This requires understanding blood typing and discrepancies in laboratory settings.
Answer
Probable ABO Group: O. Discrepancy: No agglutination. Causes: Missing antigens. Resolution: Repeat testing or review history.
Probable ABO Group: Group O. Type of discrepancy: No agglutination. Probable Causes: Weak/missing antigens or antibodies. Resolution: Repeat test, review patient history, or use alternative methods.
Answer for screen readers
Probable ABO Group: Group O. Type of discrepancy: No agglutination. Probable Causes: Weak/missing antigens or antibodies. Resolution: Repeat test, review patient history, or use alternative methods.
More Information
ABO typing discrepancies can arise due to technical errors or biological factors such as weaker antigen presence. Correctly identifying and resolving such discrepancies is crucial for accurate blood grouping.
Tips
A common mistake is assuming the absence of agglutination immediately indicates an O group without considering weak antigens.
