Blood donors make a lifesaving difference. More than 4.5 million patients need life-saving blood transfusions each year in the U.S. and Canada. And blood is a perishable resource that can be stored only for a short time. That's why blood donors are needed every day.
You may be eligible to give blood every 56 days if you are a healthy person age 17 or older (or 16 with parent or guardian permission), weighing 110 pounds or more. Although, females age 18 and younger must weigh 120 pounds or more.
Parent or guardian permission required for 16-year-old donors. Click here for the required permission form.
Before You Donate
- Get plenty of rest, drink extra fluids, eat a good meal (including iron-rich foods), and avoid alcohol.
- If okay with your doctor and medical condition, eat more salty foods than usual 24 hours before you donate.
- Avoid smoking right before you donate.
- The entire process takes about 60 minutes.
- Healthy people are eligible to donate every 56 days.
- Sign in to let us know you're here.
- Present photo ID or two forms of non-photo ID.

2. Screening Area
- Answer questions about your health.
- Mini-physical: Temperature, pulse, and blood pressure are all checked. A small drop of blood from your fingertip is taken to test your iron level.
- Drink a bottle of water to hydrate before you donate.
- A tourniquet goes on your arm above the elbow.
- A phlebotomist cleans your skin.

5. Post-Donation Station
- Take 15 minutes to sit, relax, and enjoy a snack.
- Drink plenty of fluids.
After You Donate
- Most people feel fine. Drink more nonalcoholic liquids than usual. This is important because your body replaces the liquid volume of the donated blood within 24 hours.

- If you smoke, avoid smoking for 30 minutes.
- Delay strenuous exercise until after your next regular, full meal.
