Blood tests are a basic but very informative device for our Cardiologists. They help to give an overview of your general health and allow us to assess the function of your key organs (eg. liver, kidney and thyroid function). They are also used to identify potential risk factors in the body which may cause problems with your heart in the future (eg. cholesterol levels). Blood tests are taken by our experienced and reassuring Practice Nurse who is well aware that you may be nervous about having this done. The sample is sent for analysis to a local laboratory and in most cases, the results are normally available within 24 hours.
