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.
I think within seven days includes the seventh day. â¢ Donated platelets must be used within five days of collection. I take that to mean the platelets can be used on Days 1, 2, 3, 4, and 5. But on Day 6, they have to be discarded.
