Anticoagulant Clinic – Worthing

Anticoagulant drugs are often referred to as blood-thinning drugs, and are medicines that prevent the formation of harmful blood clots by reducing our blood cells’ ability to bond together.

Staff in our anticoagulant clinics help you take the right dosage of anticoagulant drugs like warfarin as part of your treatment for conditions such as atrial fibrillation (AF) and deep vein thrombosis (DVT), or after heart valve repair or replacement surgery.

Blood samples

The clinic staff will advise you of when to have the regular blood tests you need to ensure you are taking the right dosage of medicine, and also keep you informed of what that correct dosage will be.

The blood tests you will have measure your International Normalised Ratio (INR), which is a measure of how much longer it takes your blood to clot when you are taking anticoagulants by mouth.

The dosage you are asked to take will vary according to the results of these tests.

INR results by email

We are now able to advise you of your INR results by email, which is more convenient than a letter for many people and saves the hospitals money on stationary, postage and admin work.

To register, email ACatWorthing@wsht.nhs.uk to confirm you would like results to be emailed to you. Don’t forget to include your name and contact number.

We will acknowledge your request with a test message and your most recent result, if we have it.

Please check the details of the test message and reply to it, letting us know you have received it OK and if any of the information in it is incorrect.

We will then email you all results in future.

Going on holiday?

You can also email us occasional results of INR tests taken when you are away from home – even if you are abroad.

Please keep the message heading brief and compose your message in the following format:

  • Your name
  • Your hospital number
  • Your date of birth
  • Venous INR result and date
  • Test location
  • Warfarin dose
  • Any additional information

So, for example:

Mr Joe Bloggs

Worthing Hospital Number 123456

Venous INR result 3.5 on Wed 17/06/2009

Send the message to ACatWorthing@wsht.nhs.uk.
