There are several conditions for a blood donation. For instance, you have to have a minimal weight, because they take off a minimal amount of blood for everybody. So they don't want to take off most of your blood just because you're small. If you're sick that day, they won't take your donation. They also need a minimal percentage of iron in your blood, which is VERY important.
