DVT (Deep Vein Thrombosis) Test

What is Deep Vein Thrombosis (DVT)

Deep Vein Thrombosis or DVT is a condition that occurs when a blood clot forms in one the veins deep inside the body.  The most common place for these clots to form is in leg or thigh but they can develop in other places as well.  In addition to causing pain and swelling, these clots can come loose and travel to the heart or lungs where they can block blood flow which can be life-threatening.

What are the symptoms of DVT?

Common symptoms of DVT include:

  • swelling in the foot, ankle, or leg.  Swelling usually only occurs on one side of the body
  • cramping in the leg
  • pain in the foot or ankle
  • an area os skin which feels warmer than the surrounding area
  • a section of skin which turns red or a bluish color

Not everyone with DVT will experience the same symptoms or any symptoms of all.

What are the causes of DVT?

There are a number of factors that can increase a person's risk of developing DVT.  Sitting for long periods of time can cause blood to collect in the lower part of the body which can cause a clot to form.  Injury or surgery can damage the blood vessels which narrows blood flow and make clot formation more likely.  Some medications can increase the risk of clot formation so it is important to review possible side effects with your doctor.  Other risk factors include being overweight, smoking, taking birth control pills, having a family history of DVT, and being over the age of 65.

How do I test for DVT?

There are several lab tests that can help assess your risk for DVT.  A D-dimer test measures a protein that is released when blood clots break down.  Elevated D-dimer levels can indicate frequent clot formation.  People with high Factor V Leiden test results may have an inherited disorder which causes excessive clotting.  Protein C and Protein S help regulate the body's process of forming and breaking down blood clots.  When either of these proteins is deficient, a person can be more likely to develop a clotting disorder.
