Blood Donation FAQs

Does my blood type make a difference?

Certain blood types are in greater demand (and shorter supply) than others at different periods. However, donors of all blood types are needed and welcomed!

How much blood will be taken during my donation?

A “unit” of blood is collected during a donation. This is equivalent to about one pint of blood.

  • Most adults have between 10 and 12 pints of blood in their bodies.
  • Your body will replace the lost fluids within 24 hours, and will begin to replace the lost blood cells right away.

Does donating blood hurt?

Most people say they only feel a slight pinch of the needle at the start of the donation. (Many people also report feeling great after donating because they know they've helped patients in need!)

What should I do to get ready for my donation appointment?

  • Eat a nutritious and filling meal the day of your appointment (and get plenty of calcium).

  • Make sure you are well-hydrated. Try to drink six to eight 8-ounce glasses of water the day before and the day of your donation appointment.

  • Bring a valid photo ID with you to the appointment.

  • What should I do after my blood donation appointment?

  • We encourage donors to drink plenty of good fluids (water and juices) after donating. This will help keep your body well-hydrated.

  • Eat well the day of your donation and don’t hesitate to snack if you feel hungry.

How often can I donate blood?

As long as you are healthy and continue to meet the eligibility criteria, you can safely donate every 56 days.

Can I donate if I have a tattoo?

Yes, as long as the tattoo was performed in a state regulated facility and is completely healed, you are eligible to donate.
