There are a number of medical conditions that exclude you from becoming a donor. This is to protect both your health and the health of the recipient.

You can not donate if you have:

  • Heart disease
  • Chronic lung disease
  • You can donate if you have asthma provided you have no symptoms at the time of donation and you do not require high doses of anti-asthma medication.
  • Stroke and Transient ischaemic attack (TIA)
  • Epilepsy or other central nervous system disease.
  • Cancer (even if you had this a long time ago)
  • Inflammatory bowel disease: Crohn’s disease and Ulcerative colitis.
  • Autoimmune disease (e.g. Rheumatoid arthritis, SLE – systemic lupus erythematous) if you have required treatment to suppress the condition in the last 12 months. Painkilling drugs such as non-steroidal anti-inflammatory drugs and physical therapy such as physiotherapy are not considered treatments to suppress the condition.
