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.
Apheresis platelet donors, however, must not take aspirin or aspirin-containing products 36 hours prior to donation. Aspirin reduces the potency and performance of your platelets. The more time between taking aspirin and donating blood, the better for the recipient. It is recommended that you call the donor center before you come to donate to inquire about any medications you are taking. Most times, taking medications will not keep you from donating.
