Check basic blood donation eligibility
Blood donation has eligibility criteria, and a basic check helps you know before you go. This checker uses age, weight and days since your last donation to give a basic eligibility indication.
Why the basic criteria exist
Blood donation has minimum requirements, an age range, a minimum weight, and a required gap since your last donation, that exist to protect both the donor and the recipient. A basic check against these tells you whether the common criteria are met before you make a trip. But full eligibility depends on many more factors, health, medications, travel, that only a proper screening at the donation centre assesses. This check is a helpful first indication, not a determination; the centre’s screening is what actually decides.
