What must be checked to ensure accurate pre-transfusion testing?

• A. A single sample tested in an automated instrument
• B. Two separate ABO typing interpretations by the same technician
• C. Verification of patient ID alone
• D. ABO typing must confirm historical discrepancies

Answer: (B)

To ensure accurate pre-transfusion testing, it is crucial to confirm that ABO typing interpretations are performed, ideally by two separate tests conducted by different technicians or, at the very least, in a manner that reduces the chance of errors. This double-checking process minimizes the risk of misidentification or misinterpretation that could lead to severe transfusion reactions. Testing samples from the same technician, using a single sample in automation, or relying solely on patient ID verification does not provide the level of assurance needed for such critical testing. Misidentification of blood types can have life-threatening consequences, making it essential to have corroborative evidence through independent testing. This procedural approach is grounded in best practices aimed at enhancing safety and reducing the risk of transfusion-related complications.
