What is the thawed shelf life of plasma?

5 days thawed 40 days thawed 15 days thawed 60 days thawed

Correct Answer:

5 days thawed

Explanation:

Thawed plasma has a short, defined window of effectiveness when stored properly. Once plasma is thawed and kept at cold temperatures (about 1–6°C), the coagulation factors remain functional for up to five days. After that, the activity of those factors declines and the risk of bacterial growth increases, making it less reliable for hemostatic resuscitation. Therefore the practical shelf life after thawing is five days. Longer durations listed would reflect frozen or unthawed states and aren’t used for thawed plasma. Always discard after day five and keep the product refrigerated, without refreezing once thawed.
