Cascade Regional Blood Services is committed to maintaining a safe and available blood supply and treating all potential donors with fairness, equality and respect. To that end, we strongly support ongoing research initiatives designed to determine if donor-screening alternatives based on individual behaviors, not based on sexual or gender identity, will provide equivalent or superior transfusion safety. We encourage the Food and Drug Administration (FDA) to continue its examination of deferral criteria for men who have had sex with men (MSM) to ensure the use of rational, science-based deferral periods that are applied fairly and consistently among blood donors.

There are a number of things you can do to help ensure a good donation, like drinking plenty of beverages and eating well before your donation. For more information, read our advice on how to Be Prepared.

There are a number of iron-rich foods you can add to your diet, such as fish, beans and spinach. Click here for more.
