Giving whole blood requires a waiting period of 56 days between donations; however, all we ask is for individuals to Commit for Life and donate once every quarter. If you donate plasma (your red cells are returned to you), you may donate every 28 days.
Types of Donations. Whole blood: This is collected using a single needle and a blood bag. A donor can donate every 56 days (eight weeks). This collection takes only about 7-12 minutes; the complete process takes about 20 to 40 minutes; red blood cells have a 42-day shelf-life. Platelet and platelet plus red blood cells: These are collected using a single needle with an apheresis machine.
