Blood Donation Eligibility Information
Blood Donation Eligibility Information
Basic Requirements
Most people in good health, at least 18 years old, and weighing at least 110 pounds may donate whole blood every 56 days. Please schedule your appointment today.
Health requirements
You must be in good health and feeling well on the day of your donation. When you donate, you’ll undergo a confidential screening interview and mini-health check of blood pressure, pulse, temperature, and iron level. Here are some ways you can prep for your donation.
Not everyone is eligible to donate. Some health conditions, medications, or travel may temporarily or permanently prevent people from donating blood. Read more below and for specific questions, contact our Eligibility team at [email protected] or (425)656-3077 (option 1)
Weight requirements
You must weigh at least 110 pounds. There are additional weight requirements for teen donors:
- First-time 16 or 17 year old donors who weigh at least 114 pounds may donate at Bloodworks NW donor center.
- First-time 16 or 17 year old male donors who weigh at least 114 pounds may donate at a mobile blood drive.
- First-time 16 or 17 year old female donors who weigh at least 125 pounds may donate at a mobile blood drive.
- Mobile blood drive weight requirements for 16 or 17 year olds are to improve our young first-time donors’ experience, and minimize chances of vasovagal reaction.
Age requirements
You must be at least 18 years old. There is no upper age limit.
Washington: 16 or 17 year olds donating in Washington must have a Bloodworks Northwest permission form signed by a parent or guardian to donate. Form must be printed on white paper only.
Oregon: 16 or 17 year olds donating in Oregon do not require a Bloodworks permission form, unless requested by the donor group(s).
