Can I donate blood with low blood pressure?
What this means
- Naturally low blood pressure is common and often fine.
- If your reading is below the center's range, donation may be postponed that day.
- Hydrating and eating beforehand helps.
What to do next
Eat, hydrate, and rest before your appointment, then have your reading taken.
When to call the center: Call if you frequently feel faint or dizzy.
Why this rule exists
A safe reading helps prevent dizziness or fainting during and after donation.
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.
