I was deferred for weight or age. Can I donate later?
What this deferral usually means
Donation collects a standard amount of blood, so a minimum weight, commonly 110 pounds, helps keep it safe for you. Age and consent rules vary by state.
What to ask the center
Ask the exact weight requirement, and for younger donors, whether a height and weight table applies.
When you can try again
When you meet the requirement. For age, once you reach the eligible age or have the right consent form.
Set a return reminderPrepare for your comeback
- Confirm the exact minimum weight at your center
- For donors aged 16 or 17, bring a consent form where required
- Eat well and hydrate before your visit
