What is the standard acceptable color for anti-A grouping serum?

Explanation:
Color coding of grouping sera helps prevent mix-ups in ABO testing. The anti-A grouping serum is typically labeled blue, a convention used to distinguish it from other grouping reagents (for example, anti-B or control sera may use different colors). The color has no bearing on its ability to detect A antigen; it’s simply a labeling scheme to ensure the technologist selects the correct reagent quickly and avoids confusing anti-A with other reagents. Therefore blue is the standard acceptable color for the anti-A grouping serum. Red, green, or yellow are not the standard colors used for this reagent in most practices.
