Most healthy individuals can donate to the ASBP; however, there are some reasons a person may be deferred from donating temporarily, indefinitely, or permanently. In general, a person must weigh at least 110 pounds, be at least 17 years of age (age may vary by state and weight based on type of donation giving. Contact your local ASBP blood donor center for details), have been feeling well for at least three days, be well hydrated and have eaten something prior to donating.
