A Blood Test Called A D-dimer Is Used To Rule Out Possibility Of You Having a Blood Clot

A blood test called a D-dimer can be used to assist in ruling out the possibility of a dangerous blood clot.

Your body performs a number of actions to cause your blood to clot up when you get cut. Without it, you’d keep bleeding and have a much bigger issue to deal with. It’s a regular component of healing.

You no longer require the clot once the bleeding has stopped. Your body then moves in a number of opposite directions to dissolve the clot.

After all of that, you still have certain things floating about in your blood, just like how you would have wood dust all over the place during a construction project.

D-dimer is the name of one of such byproducts. It is a protein’s component. Usually, it disappears with a little bit of time.

But if you have a significant clot, such as from deep vein thrombosis (DVT), you could have high amounts of D-dimer in your blood.

When you have a deep vein clot (DVT), it commonly occurs in your legs and can cause major issues.

In order to determine whether you might have a blood clot, your doctor may conduct this test, which measures the amount of D-dimer in your blood. This test may also be referred to as:

  • D-dimer fragment test
  • Test for fibrin degradation fragments

Do I Need This Test Now?

Certain tests enable you to determine with certainty what illness or condition is to blame for your symptoms. To completely rule out a specific ailment as the cause, other tests are more helpful.

Depending on what your doctor wants to see from the D-dimer test, it can be used in either direction.

DVT and other conditions must be ruled out by: When your doctor suspects something else is causing your symptoms and wants to swiftly rule out these reasons, the D-dimer test is most helpful.

  • DVT, which can result in leg edema, discomfort, or redness
  • PE stands for pulmonary embolism, a blood clot that has reached the lungs and may cause symptoms such as coughing, rapid heartbeat, chest pain, and difficulty breathing.

In this situation, the test is only beneficial if you don’t have many blood clots. A blood clot may not necessarily indicate a positive D-dimer test.

There will be more tests required to verify that. A new set of tests will be required if your chances of getting a clot are higher. More likely to develop a clot are:

  • Antiphospholipid syndrome, a disease in your immune system
  • Clotting diseases that you’re born with
  • Major surgery, such as a knee replacement
  • Major injury, such as a broken leg
  • Long periods of sitting or lying down, such as a long plane ride or hospital stay
  • Pregnancy or if you recently had a baby
  • Some cancers

D-dimer can also be used to assist test for a condition known as disseminated intravascular coagulation (DIC), in which blood clots develop in tiny blood vessels all over your body and result in bleeding. It might endanger life.

It’s also used to evaluate how well DIC treatment is working. D-dimer levels decreasing is a sign that the therapy is effective.

What occurs throughout the test?

A D-dimer test does not require any extra preparation on your part. Your doctor takes a little blood with a fine needle.

When the needle is inserted, you can feel a squeeze or stinging. Where the blood is drawn, you might have some soreness or bruising, but that is typically all.

Usually, you see effects right away. In emergency rooms, this test is frequently applied.

What Do the Findings Indicate?

The test may be performed differently by different labs, therefore be aware that what is normal may change. Your doctor can explain your results to you in more detail.

If your test result is “negative,” you probably don’t have a blood clotting issue, such as DVT.

If the result is “high,” further tests will be required to determine whether you have a blood clot. Your presence of DVT or PE cannot be verified by this test. It can only aid in eliminating them.

In addition to a clot, additional conditions like these could potentially cause a high result:

  • Infection
  • Liver disease
  • Some cancers
