Protein S Deficiency (PSD) is a rare blood disorder that affects just a few thousand people worldwide. It is one of several known risk factors for thrombophilia and can increase the risk of blood clots such as Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE).
Information about thrombophilia is widely available on the Internet but it tends to focus on the more common risk factors such as Factor V Leiden, Antithrombin III Deficiency or Protein C Deficiency. If there is any specific mention of Protein S Deficiency it is likely to be brief, because after all, PSD is a rare condition.
Our aim is to complement the other information sources by focusing on details specific to PSD and to improve understanding and awareness of Protein S Deficiency. We obtain our information from a variety of sources such as medical literature, other sites, and from our online discussions which includes personal experiences and advice from our doctors.
However we run our web site without the support of any medically qualified staff and there are limitations to the way health information or advice can be provided over the Internet.
