What does a blood group discrepancy suggest in a patient’s serum sample?

• A. Need for re-evaluation of test results
• B. The sample may not represent the patient’s true type
• C. Potential technical error in testing
• D. Chance of transfusion reaction

Answer: (A)

A blood group discrepancy indicates that there is a mismatch between the expected and observed results in blood typing tests. This could suggest a need for re-evaluation of test results to ascertain the cause of the discrepancy. It emphasizes the importance of verifying the results to ensure that the patient has been accurately typed. Discrepancies may arise due to various factors, such as unexpected antibodies in the serum or subgroups of blood types not typically detected in routine testing. By recognizing a discrepancy, healthcare professionals must further investigate to determine the underlying reason, which might involve repeating tests, reviewing the patient's history, or considering potential inherited variations in blood groups. This diligence is crucial, especially in scenarios like transfusion, where accurate blood typing is paramount to prevent adverse reactions. While the other options have relevance, they do not encompass the broader clinical implication that evaluation of test results is essential when discrepancies arise. Option B suggests the sample might not reflect the true blood type, while this could be a certain factor, it does not capture the necessity of re-evaluation. Option C points toward a technical error, and option D references the potential risk of a transfusion reaction, which is indeed a concern but doesn't directly address the immediate implication of a discrepancy leading to a re-assessment
