Factor V Liden

What is Factor V Leiden?

When you get a cut, your body creates a clot to stop the bleeding in minutes. Factor V Leiden, also known as FVL, is a mutation in your genes that helps your body to form clots and keep such process functioning properly.

Factor V (F5) is a type of protein found in the blood clotting system, which allows several metabolic procedures to take place for creating blood clots. When it works properly, the protein helps your body form the blood clots at the moment when it is bleeding due to a cut or scratch.

What is Factor V Leiden Test?

A Factor V Leiden test is ordered to find out the risk of forming excess blood clots. If an individual has an inborn gene mutation that forms more blood clots, and they don’t break up naturally, it is called a hypercoagulable condition. Unnecessary clots in the bloodstream can lead to some serious health problems if they don’t break up. The excess clots travel through the bloodstream and form a blockage in the arteries in your lungs.

The test is aimed at determining if an individual has a high risk of forming blood clots. It is generally administered through two separate diagnostic procedures that examine an individual’s DNA to check the mutations.

When the Test is Ordered?

Many people fail to know that they have a factor, V Leiden, because a blood clot can be negligible or a life-threatening condition. But there are always some common symptoms that point to the excess blood clots in your body.

Below are the signs of a clot:

  • Pain
  • Redness
  • Swelling
  • Warmth

Pulmonary embolisms can be a chronic condition as it happens when the blood clots travel through the bloodstream and damage the lungs. In such conditions, you may experience the following symptoms:

  • Chest pain or discomfort
  • Problem in breathing
  • Irregular heartbeat
  • Very low blood pressure
  • Dizziness

In addition, your doctor may also order for the test if you have:

  • Deep venous thrombosis (DVT) or (VTE) before the age of 50
  • Blood clots in unusual body parts like kidney, the brain, in the eye veins
  • A family history of DVT or VTE

It is a simple blood test that is used to find out the Factor V Leiden mutation.
