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.
Plasma is collected simultaneously with a platelet donation and is collected at select American Red Cross Blood Donation Centers only. You can donate every 28 days, up to 13 times per year. The average donation takes 1 hour and 15 minutes. If you are a platelet/plasma donor, you can still give regular whole blood or Power Red.
