Platelet function after shipment of room temperature platelet concentrates

Area of Science:

• Transfusion Medicine
• Hematology
• Biopreservation

Background:

• Platelet concentrates are crucial for treating bleeding disorders.
• Maintaining platelet function during storage and transport is essential for efficacy.
• Current blood bank storage involves continuous agitation and strict temperature control.

Purpose of the Study:

• To evaluate the impact of shipping conditions on platelet concentrate function.
• To compare platelet function after shipping at different temperatures (22°C vs. 4°C) and durations.
• To assess if shipping affects platelet function compared to standard blood bank storage.

Main Methods:

• Platelet concentrates were stored for 48 or 72 hours.
• Shipment was conducted for up to 10 hours at either 22°C or 4°C.
• Platelet function was assessed using hypotonic shock response, aggregation, and serotonin uptake.
• Compared shipped samples to those stored under optimal blood bank conditions.

Main Results:

• Platelet function was better maintained at 22°C compared to 4°C during shipping.
• A significant drop in hypotonic shock response was observed in shipped platelets after 72 hours.
• Overall, shipping did not lead to a significant impairment of platelet function compared to standard storage.

Conclusions:

• Shipment of platelet concentrates under the tested conditions is feasible.
• Temperature control during transport is important, with 22°C being preferable to 4°C.
• Platelet function is largely preserved following short-term shipment, supporting its use in transfusion medicine.
