REW is short for Ruby Eyed White. You may hear breeders call them REW (Roo) for a nickname. Example That's a nice Roo you've got there. They are rabbits with the Albino gene and hide their true color. The Albino Gene isn't so much a color as it is a color hiding gene.
Platelets. You can donate platelets once in a seven day period and up to 24 times a year. You must wait at least 7 days after donating platelets before donating whole blood. After an automated double red cell collection, you must wait 112 days before donating again.
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. If you donate platelets (your red cells and most of your plasma are returned to you), you may donate every seven days, with a maximum of 24 times per year.
