Final answer:

Delay in adding AHG reagent can cause a false-negative result in antiglobulin techniques.


Explanation:

Addition of AHG reagent is delayed for 40 minutes or more after final saline wash may cause a FALSE-NEGATIVE result with antiglobulin techniques. For example, if the AHG reagent is added late, it might not adequately detect the antigen-antibody reactions, leading to a false-negative outcome. This delay can impact the accuracy of the test results and hinder the identification of important antibodies present.
