D-Dimer Test Overview

A D dimer blood test is a simple test which measures D-dimer levels in your blood. D-dimer is basically a small protein that is formed when there is breakdown of a blood clot in your body.

Whenever there is any injury to our body (tissue and blood vessels) clotting process helps to stop bleeding. This clot is also called a thrombus. Once the tissue is healed and this clot is not required, it is broken down into certain products. One of these products is D-dimer

If there is a blood clotting disease (also called thrombotic disorders) in your body, blood clots can easily form even without any triggering factor like injury, and these clots don’t easily break down when they should. Hence, these blood clots can be very dangerous and can even be life-threatening.

In normal conditions, D-dimer level is undetectable, but if certain thrombotic disorders are present, its level rises significantly. The D Dimer test price is approximately between INR 900-1800.

Why is D Dimer test prescribed?

The D-dimer blood test is used to diagnose blood-clotting diseases such as

Disseminated intravascular coagulation (DIC)- This is a disorder where multiple blood clots form in the body in various organs and damage these organs.
Deep vein thrombosis (DVT)- It is a condition in which blood clots in deep veins of the body, mostly those of the legs.
Pulmonary embolism (PE)- It is a condition in which blood clots block the arteries in the lungs
Stroke- It is a condition caused by to blockage of blood supply to the brain because of blood clots

D D-dimer test is also done to monitor treatment of the above-mentioned conditions

What are the components of this test?

D-dimer test is usually done if your health care provider suspects blood-clotting disorders. If your blood level of D-dimer is low, it shows that it is very unlikely that a thrombus is present in your body. But high levels of D-dimer require further investigation (like Doppler ultrasound, CT angiography, etc), to find out the underlying condition, trigger factors and site of thrombus.

D-dimer test is also done along with prothrombin time, fibrinogen, and platelet count to diagnose disseminated intravascular coagulation (DIC).

Procedure and prerequisites

The sample for the D-dimer test is taken from blood (serum) by inserting a small needle into a vein in your arm. A small amount of blood is then collected in a test tube or vial. You may feel a little pain due to a needle prick. You may resume your daily activities once the bleeding stops from the collection site.
