What approach is taken if a unit of platelets is noted to have a significant drop in pH during storage?

In the context of platelet storage, the pH level serves as an important indicator of the quality and viability of the platelets. A significant drop in pH can indicate bacterial contamination or metabolic changes that could compromise the safety and effectiveness of the platelet unit. When such a drop is detected, the appropriate response involves ensuring patient safety.

Disposing of the unit is a necessary course of action because continuing to use a unit with compromised quality could pose risks to recipients, such as transfusion reactions or infections. This decision underscores the importance of maintaining stringent safety standards in blood banking and ensuring that only the highest quality components are prepared and issued to patients.

In contrast, options that involve reprocessing, issuing without concern, or quarantining for monitoring do not address the potential immediate risks associated with a significant drop in pH. These alternatives may delay proper action, thereby increasing the likelihood of patient exposure to compromised products. Thus, disposing of the unit is the most responsible and safest approach to ensure that all transfused products meet established safety criteria.
