It depends on where the testing is done. If your ferritin result is low on a test ordered by your doctor we require you to take a break from all donations for six months from the date of your test. You can return after 6 months if your investigations and treatment are completed. If you’re tested by Lifeblood and the result is low, you’ll receive a letter to let you know what you’re eligible to donate.
We manage eligibility for donors who have had a ferritin test performed by their doctor differently from how we manage a result from Lifeblood testing. This is because we perform ferritin as a screening test, which is a test performed in well individuals. Your doctor will usually perform a ferritin test as a diagnostic test because of symptoms or some other reason that suggests you need your iron stores checked.
