Miscarriage or thrombotic risk profile

Why would I take this test?

Deep vein thrombosis (DVT) is a blood clot in a vein, typically the leg, and it can be a serious condition. Symptoms include a throbbing or cramping pain in one leg, swelling of the leg, and a warming and reddening of the area. A DVT can also occur in your arm or tummy.
You are at higher risk of DVT if you’re:

• over 60

• overweight

• a smoker

• had a DVT before

• dehydrated

• have cancer, heart conditions or varicose veins

The risk can increase when you travel, particularly if you are at high altitude or don’t move around much, which includes any long journey (more than 3 hours) by car, train or plane.

How a test is done?

Our phlebotomist will tie a rubber band to your upper arm to make the veins more visible. They will swab to clean the arm, then a sterile needle attached to a tube is gently inserted into the vein and the blood is drawn into a vial (or vials if more than one test has been requested). Only one needle is used regardless of the number of tests or vials requested. The needle is removed, a plaster applied, and it’s done. You might get a small bruise around the needle mark.

Please wear loose clothing (for easy access to your arm) and let us know a preferred arm.

You can continue to take regular medication but check with your doctor whether any of your medications may affect test results.

It's easier to draw blood when:

• you are hydrated – please drink some water, especially in hot weather and for morning blood draws

• you are warm – please keep warm before the test

Fasting is not required

A non-fasting test means:

• you can eat and drink as normal before the test

• it’s advised not to drink alcohol before the test

• you can continue to take regular medication but check with your doctor whether any of your medications may affect test results

Can I have someone with me?

Of course, if that makes you more comfortable, you may have a friend or relative accompany you during a blood test.

When will I get my results?

What can this test detect?

This screen checks for thrombotic risk (where your body has an increase chance of blood clots) and includes:

• full blood count (FBC) and coagulation profile

• Factor II Prothrombin gene

• Factor V Leiden gene

• antithrombin III

How do I get my results?

The certified laboratory report is emailed to us, and we can either:

• email directly to you

• email directly to you and/or to your GP. We will need your written consent to share any test results, but we will discuss this with you when you book your appointment

• give it to you in person at the clinic

We highly recommend you consult with your clinician to explain test results. They can also take into account your medical history and advise you on next steps.
