Deep vein thrombosis (DVT)

You can give blood if you had a DVT when you are completely recovered and you are off all anticoagulant treatment for at least 7 days. If you have had more than one episode of DVT, you cannot give blood

If you had an axillary vein thrombosis (i.e. in your upper limb) you cannot give blood, even if you only had one episode.

If you have an inherited condition that makes it more likely that you would have a DVT, such as Factor V Leiden or Protein C or Protein S deficiency, and you have not had a DVT, you can give blood. However, if these conditions caused even one DVT, you cannot give blood.
