Platelets prepared in a polyolefin type container, stored at 22 - 24 C in 50 mL of plasma, can be used for up to:

Platelets prepared in a polyolefin type container and stored at 22 - 24°C in 50 mL of plasma have a shelf life of up to 5 days when following proper storage conditions. This duration is established based on studies that have demonstrated the stability and functional viability of platelets when maintained in suitable containers under regulated temperatures.

The polyolefin material helps in maintaining the integrity of the platelet concentrate, allowing for adequate gas exchange while minimizing the risk of contamination or degradation that could shorten viability. Five days of storage provides flexibility in the use and management of platelet transfusions in clinical settings, allowing healthcare providers to administer life-saving components while also accommodating logistics related to blood bank operations and patient needs.

In comparison, shorter durations, such as 24 hours, 48 hours, and 3 days, do not align with current guidelines and research-supported practices regarding platelet storage, making them incorrect choices for this scenario.
