I was deferred for low iron. When can I donate again?

Usually temporary
Quick answerLow iron is one of the most common reasons people are asked to wait, and it is almost always temporary. With a little time and some iron-rich eating, most donors come back.

What this deferral usually means

Your hemoglobin was below the level needed to donate safely that day. It protects you from becoming depleted by giving.

What to ask the center

Ask what your reading was and what level you need to reach, and whether they recommend an iron supplement.

When you can try again

Often a few weeks to a couple of months. Rebuilding iron takes time, so do not rush back the very next week.

Set a return reminder

Prepare for your comeback

  • Eat iron-rich foods like lean red meat, beans, lentils, and spinach
  • Pair iron-rich foods with vitamin C to help absorption
  • Ask your clinician whether an iron supplement is right for you
  • Hydrate well in the days before your next visit
