What is not a requirement for the electronic crossmatch procedure?

The electronic crossmatch procedure requires that the recipient's ABO type be determined accurately before the selection of compatible blood products. Having concordant results of at least two determinations of the recipient's ABO type is vital for ensuring the accuracy and reliability of the blood typing. This requirement helps to eliminate potential errors that could arise from a single determination, which might not reflect the actual blood type due to factors such as operator error or sample degradation.

Although one determination is important, relying on a single test does not provide the same level of confidence as multiple concordant results. Therefore, having at least one determination does not meet the standard required for the electronic crossmatch process. The other requirements contribute to the safety and effectiveness of the procedure by ensuring compatibility and validating system performance, which are critical to preventing transfusion reactions.
