Blood donors:
New blood or plasma donors can make their first donation any time after their 16th birthday and before their 71st birthday.

You must not have any traces of alcohol in your blood at the time of your donation (e.g. not have consumed alcohol on the day of donation).
You can donate if you have mild hay fever or other mild allergy to a food or environmental substance. Taking a medicine to control symptoms will not affect your ability to donate.

If you have a history of moderately severe allergic reactions in the past but you are otherwise fit and well, with no local reaction, you can donate.
After a moderate allergic reaction to a medicine you will need to wait for 12 months before donating. After a severe allergic reaction or anaphylaxis you may donate provided you are well on the day and will not be exposed to anything you are allergic to (e.g latex)
As long as you do not have a cancer and meet the criteria for blood pressure and pulse rate, you can donate.
If you have previously been treated for iron, B12 or folate deficiency and your haemoglobin is normal, you may be able to donate blood or plasma.
If vitamin B12 (tablets or injections) are taken to prevent deficiency related to diet or as an over-the-counter medication, you may be able to donate blood or plasma. If vitamin B12 is prescribed and given as an injection by a registered health professional to treat deficiency related to diet, you will need to wait 90 days after your last injection before you can donate.
If you are having medical investigations for anaemia, it will be necessary to wait until the investigation is completed. Presence of persistent anaemia and some specific types of anaemia, such as pernicious anaemia, may result in permanent deferral from donating.
Please call 0800 GIVE BLOOD (448 325) and ask to speak with a nurse if you have any questions.
Although your previous symptoms, which required an angioplasty may have settled, you can't give blood in the future as you may not be able to tolerate 470mL blood withdrawal

You must be in good health at the time of your donation.
If you have travelled independently (not in an organised tour) for 4 consecutive weeks or more to a country that is considered a high risk for contracting Chaga’s disease, you will be tested for the T. Cruzi antibody. You may still be eligible to donate plasma.

Please call your local Donor Centre or 0800 GIVE BLOOD (0800 448 325) and ask to speak with a nurse.
If you are pregnant, you cannot donate blood. This is to avoid any stresses on the mother's or baby's circulation, or on the mother’s iron levels. Following pregnancy, you will not be eligible to donate blood or plasma for as many months as your pregnancy was long. In most cases, this is 9 months.
See Miscarriage or Termination.

If you have not fully recovered, we ask that you allow 3 months from your full recovery before donating.
Even if you wear a condom each time, if you are participating in sexual activities that are considered a high risk of HIV transmission, you will need to wait 3 months until you can donate. Condoms reduce the risk, but there is always a very small risk, if the condom breaks or is not used properly, of transmission.
The relative risk of HIV transmission is much higher with a transfusion of infected blood than with sexual intercourse with an infected partner.
This justifies a more stringent approach to risk reduction for transfusion.
If conjunctivitis is due to infection you will need to wait for 7 days after the condition is fully settled and you are off antibiotics.
If allergies cause your conjunctivitis, please see the Allergies criteria.
