Bandages keep the wound clean, keep harmful bacteria out, and maintain moisture to prevent your skin from drying out. Bandages should be changed daily.
You must wait at least eight weeks (56 days) between donations of whole blood and 16 weeks (112 days) between Power Red donations. Platelet apheresis donors may give every 7 days up to 24 times per year. Regulations are different for those giving blood for themselves (autologous donors).
