Who Can’t Give Blood?
Although most people are potentially able to give blood, some are not.
There are a variety of reasons why we might ask you not to give blood, but they fall into two main categories. Firstly, if evidence suggests that donating blood could potentially harm you, then to protect your safety we would ask you not to donate. Secondly, if evidence suggests that your donation could potentially harm the patient receiving it, then we would ask you not to donate.
This would include the situation where a specific behavior may have put you at a higher risk of an infection which could be transmitted to a patient by blood.
If you are not able to give blood we know this can be disappointing. However, we hope you will understand that our overriding responsibility is to ensure the safety of donors and the safety of blood for patients.
You should not give blood if:
- You’ve already given blood in the last 12 weeks (normally, you must wait 16 weeks).
- You have a chesty cough, sore throat or active cold sore.
- You’re currently taking antibiotics or you have just finished a course within the last seven days or have had any infection in that last two weeks.

Travel abroad
Please wait 6 months after returning from a malarial area before giving blood. Please also tell us if you have visited Central/South America at any time. (Those who’ve had Malaria, or an undiagnosed illness associated with travel, may not however be able to give blood.)
The special problem of HIV and Hepatitis viruses
- Every single blood donation is tested for HIV (the virus that causes AIDS) and hepatitis B and C.
- Infected blood isn’t used in transfusions but our test may not always detect the early stages of viral infection.
- The chance of infected blood getting past our screening tests is very small, but we rely on your help and co-operation.
- People who carry these viruses may feel healthy for many years.
You should never give blood if:
- You have ever had syphilis, HTVL (Human T – lymphotorpic virus), hepatitis B or C or think you may have hepatitis now
- You’re a man who’s had sex with another man, even safe sex using a condom. For more information click here.
- You’ve ever worked as a prostitute.
- You’ve ever injected yourself with drugs – even once.
You should not give blood for 12 months after sex with:
- A man who has had sex with another man (if you’re a female).
- A prostitute.
- Anyone who has ever injected themselves with drugs.
- Anyone with haemophilia or a related blood clotting disorder who has received clotting factor concentrates.
- Anyone of any race who has been sexually active in parts of the world where AIDS/HIV is very common. This includes countries in Africa.
- Please do not give blood if you even think that you need a test for HIV or hepatitis, or if you had sex in the past year with someone you think may be HIV or hepatitis positive.
- Never give blood to get an HIV test.
- Donors can get further information about these and other issues by contacting the special doctors. Information is provided on who can and cannot give blood, how to become a blood donor and where to donate.
