Information and Guidance

You can donate whole blood every 56 days (about every two months). Plasma and platelet donations have different intervals.

Typically, a whole blood donation is about 1 pint (approximately 470 mL).

Most blood donation centers require donors to be at least 16 or 17 years old, depending on local regulations.

One pint of blood can save up to three lives, as it can be separated into red cells, plasma, and platelets.
