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)

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.
