5-7 daysPlatelets are best stored at room temperature, and have a shelf life of 5-7 days. Refrigerated red cells can be stored for 42 days, and frozen plasma for up to a year. That's why platelet donations are always needed, every day.
The antibodies could be harmful if transfused into certain patients. The antibodies are present in plasma — and platelet donations contain a high volume of plasma, so our current efforts are directed at screening blood samples from female platelet donors to test for the HLA antibody.
What Conditions Would Make You Ineligible to Be a Donor? You will not be eligible to donate blood or platelets if you: Have tested positive for hepatitis B or hepatitis C, lived with or had sexual contact in the past 12 months with anyone who has hepatitis B or symptomatic hepatitis C.

Does donating platelets hurt? Will it make me feel sleepy? Most people say they only feel a slight pinch of the needle at the start of the donation. Because platelet donors get their oxygen-carrying red cells back, donors report feeling less tired than after giving blood.
