Please note: If the county where you plan to donate has regulations that require you to quarantine for participation in any high-risk activities related to COVID-19 (e.g., long-distance traveling), we ask that you please wait to donate until you have observed the required quarantine period.

Blood Donation: How it Works

Preparing to donate

Before your appointment:

  • Always be sure to drink plenty of water before donating blood!
  • Eat an iron-rich meal. Eating enough iron is essential to ensuring that your hemoglobin level is right for donating. You can check out some tips on getting enough iron here.
  • Bring your donor ID. If you have a donor ID, be sure to bring it with you to your appointment. First-time donors or returning donors without a donor ID card should bring a valid state-issued photo identification.

Avoid alcohol and fatty foods for 24 hours, and aspirin (if donating platelets) for 48 hours, before your donation.

The Donation Process

Congratulations, you made an appointment to donate blood and save lives! So what happens now? There are four basic steps to every blood donation:

  1. Registration
  2. Medical History
  3. Donation
  4. Rest & Refreshments

After your blood donation:
