What is the age requirement to donate blood?
What this means
- 16-year-olds can often donate with a parent or guardian's consent, depending on the state.
- 17 and older can usually donate without consent.
- Older donors are welcome if they are in good health. Some centers ask for a clinician's note.
What to do next
If you are 16 or 17, check your state's consent rules and bring a signed form if needed.
When to call the center: Call if you are unsure about your state's rules for younger donors.
Why this rule exists
Age rules balance donor safety with state consent laws.
This is general educational guidance, not a final eligibility decision. Donation centers make final eligibility decisions during confidential screening. Rules may vary by center, donation type, location, and current policy.
