If you are a National Health Service staff member, on National Health Service premises, (this includes GP surgeries), or you are a state registrered healthcare practitioner, your patient will be allowed to donate blood.

If you are not, and you needle a patient, both you, and they, must be aware that they will have to wait 4 months before they are able to give blood again.

If a patient does wish to give blood, within the 4 month period, you may treat them, but must use non-invasive methods of treatment, such as ear seed, moxa etc.
