Every blood donor is a hero. One generous donation can save multiple lives. If you have never donated blood before, or if it has been a while, now is a perfect time to roll up your sleeve.

A constant need

Every two seconds, someone in the U.S. needs blood. Blood is needed every day of the year. Blood is essential for emergencies, such as when someone experiences a severe injury in a car accident. It is also needed daily for various medical procedures, including cancer treatment, surgery and blood transfusions. By donating blood regularly, you can help ensure that blood is available when needed.

Ready to donate

Donation centers work to ensure that blood donations are safe for both patients and donors. You can help by donating when you are in good health and feeling well.

Some blood donation centers offer more than one type of donation.

• Whole blood. This standard donation involves just taking your blood as it is, without sorting for specific types of cells. You must be at least 16 years old in most states and weigh at least 110 pounds.

• Power red. A phlebotomist can withdraw twice as many blood cells with this donation. There are different age, height and weight requirements for male and female donors.

• Plasma. This advanced donation is also worth considering, particularly if you have the AB blood type. Medical teams can transfuse AB blood into any other type of blood. Donors must be at least 17 years old in most states and weigh at least 110 pounds.

• Platelet. This is another type of advanced donation, which involves both arms and a unique collection process. Platelets help create clots and stop bleeding in patients. Donors must be at least 17 years old in most states and weigh at least 110 pounds.
