Samples, Donation and Component supply

NHSBT accepts individuals with genetic haemochromatosis as blood donors once they are in the maintenance phase of the condition with no associated complications. The form is for use by hospital clinicians referring a patient to NHSBT. It requires the patient’s signature as confirmation of their agreement. Please return the completed form to the Clinical Support Team at your local NHSBT Centre.
