What Bloodworks Northwest Does

Bloodworks Northwest is a regional blood bank and nonprofit organization that collects blood donations, tests them, and distributes them to hospitals and medical centers across Washington and northern Idaho. When you donate blood through Bloodworks Northwest, your donation goes into their inventory and is used for patients who need transfusions during surgery, treatment for blood disorders, trauma care, or other medical emergencies.

Bloodworks Northwest operates donation centers in Seattle, Tacoma, Spokane, and several smaller communities. They also run mobile blood drives at workplaces, schools, and community events. The organization tests every donation for blood type, infectious diseases, and other safety markers before it enters the hospital supply chain.

Who Can Donate Blood

To donate whole blood through Bloodworks Northwest, you must be at least 17 years old and weigh at least 110 pounds. You also need to be in generally good health on the day you donate — no fever, cold symptoms, or recent illness. If you are taking antibiotics, you typically need to wait until you finish the course and feel well before donating.

Certain medical conditions and medications prevent donation. These include active cancer, heart disease, bleeding disorders, and some autoimmune conditions. If you take blood thinners like warfarin or apixaban, you cannot donate. Recent travel to countries with malaria or other tropical diseases may also disqualify you temporarily.

Bloodworks Northwest screens all donors with a health questionnaire and a brief physical exam (blood pressure, temperature, and a finger-stick hemoglobin test) on the day of donation. The staff member will ask about your medical history, medications, recent travel, and tattoos or piercings. Be honest in your answers — this protects both you and the patients who receive your blood.

Types of Blood Donations

Whole blood donation is the most common type. You give about one pint of blood, which takes 8 to 10 minutes. You can donate whole blood every 56 days. This is the donation type most people think of when they imagine giving blood.

Platelet donation (also called apheresis) uses a machine to separate platelets from your blood and return the rest to your body. Platelets are used for cancer patients and people with bleeding disorders. A platelet donation takes about 90 minutes and you can donate every 2 weeks, up to 24 times per year.

Plasma donation collects the liquid part of your blood, which contains clotting factors and antibodies. Plasma donation also uses an apheresis machine and takes about 90 minutes. You can donate plasma every 2 weeks.

Bloodworks Northwest will tell you which type they need most when you call or visit their website. Platelet and plasma donors are especially valuable because the demand is high and the supply is limited.

How to Schedule and Prepare for Donation

Visit the Bloodworks Northwest website and use their online scheduler to find a donation center or mobile drive near you and book an appointment. You can also call their donor line at 1-800-398-7888 to speak with someone who can help you find a location and time that works for you.

Before you donate, eat a meal and drink plenty of water in the hours before your appointment. Avoid alcohol for 24 hours before donation. Wear comfortable, loose-fitting clothing so the staff can easily access the vein in your arm. Bring a photo ID and proof of your Social Security number or a recent utility bill with your address.

Plan to spend 30 to 45 minutes at the center for a whole blood donation (longer for platelet or plasma). The actual collection is quick, but registration, screening, and recovery time add to the total. After donation, sit in the refreshment area for at least 10 minutes and have juice and a snack before you leave.

What Happens to Your Blood After Donation

Once you donate, Bloodworks Northwest takes your blood to their testing laboratory. Every donation is tested for blood type (A, B, AB, or O and Rh positive or negative), infectious diseases including HIV, hepatitis B and C, syphilis, and other pathogens. This testing takes several days.

After testing confirms the blood is safe, it is labeled with your blood type and stored. Whole blood is refrigerated and lasts about 42 days. Platelets last only 5 days, which is why platelet donors are in constant demand. Plasma can be frozen and stored for up to one year.

Bloodworks Northwest distributes blood to hospitals throughout Washington and northern Idaho based on patient need. A single donation can help multiple patients — whole blood may be separated into red cells, plasma, and platelets, each used for different medical purposes.

Bloodworks Northwest Donor Rewards and Support

Bloodworks Northwest runs a donor loyalty program where you earn points for each donation. Points can be redeemed for merchandise, gift cards, or entries into drawings for larger prizes. The program is free to join and you enroll when you donate.

Bloodworks Northwest also offers a text message reminder service so you do not forget your next donation appointment. You can opt in when you schedule or at any time through your donor account on their website.

If you have a rare blood type or are a frequent donor, Bloodworks Northwest may contact you directly when they have an urgent need. Regular donors also receive priority scheduling during high-demand periods.

Common Reasons Donations Are Deferred

A deferral means you cannot donate on that day, but you may be able to donate later. Common temporary deferrals include recent travel (usually 3 months for certain countries), recent tattoo or piercing (usually 3 months), recent vaccination (varies by vaccine type), and low hemoglobin on the day of donation.

If you are deferred, ask the Bloodworks Northwest staff when you can return. Many deferrals are temporary and you will be able to donate in a few weeks or months. Some donors are deferred permanently due to medical conditions or risk factors, and the staff will explain this clearly if it applies to you.

Frequently Asked Questions

How often can I donate?

You can donate whole blood every 56 days (about 8 weeks). Platelet and plasma donors can donate every 2 weeks. The waiting period allows your body to replace the blood cells or plasma you gave. Bloodworks Northwest tracks your donation history and will tell you when you are may be able to access to donate again.

Can I donate if I am on medication?

Most common medications do not prevent donation, including blood pressure medicine, thyroid medication, and birth control. Blood thinners like warfarin and apixaban do prevent donation. Antibiotics require you to wait until you finish the course and feel well. Tell the Bloodworks Northwest staff about all medications you take during your screening.
