D-Dimer test is used to identify the presence of blood clots in an individual to rule out the actual cause. This test is used to detect the underlying cause of blood clotting such as deep vein thrombosis, pulmonary embolism, major surgeries, pregnancy, diseases of the heart, and liver, etc. This test can also be used to assess the progression of the treatment for DIC (Disseminated Intravascular Coagulation).
What is D-Dimer, Deep Vein Thrombosis, Pulmonary Embolism?
D-Dimer is a free-floating protein produced after the completion of the blood clotting process. Under normal conditions, the concentration of this protein is very low. The increased concentration of this protein may indicate the presence of internal injury or blockage in the blood vessels. D-Dimer levels may also be found elevated after injuries, major surgeries, or if you have heart and/or liver diseases.
The blockage of one or more deep veins (Blood vessels) in the body is called Deep Vein Thrombosis. The symptoms include leg pain, swelling, and sometimes even have no symptoms at all. Deep vein thrombosis (DVT) can develop after surgeries, internal injuries, or other conditions.
The blockage of blood vessels supplying blood to the lungs is known as pulmonary embolism. Pulmonary embolism occurs when the smaller blood clots reach within the tiny blood vessels of the lungs and get stuck. These type of clots may originate from legs or other parts of the body. The symptoms may present as chest tightness, difficulty breathing, dry cough, chest pain, and rapid or irregular heartbeat.
Disseminated intravascular coagulation is a medical condition in which the proteins involved in the blood clotting process become overactive and form clots. These clots may block the blood supply to the vital organs such as the liver, kidneys, brain, and heart. Your doctor may prescribe medicines for controlling this condition.
Why is this test performed?
The doctor may ask you to undergo this test if you are suffering from conditions such as deep vein thrombosis or pulmonary embolism. If symptoms like leg pain, leg swelling, chest pain, chest tightness are seen in an individual without any definitive cause, the doctor may recommend this test.
Inform your doctor if you are on any medications, have any allergies or underlying medical conditions before your D Dimer test. Your doctor will give specific instructions depending on your condition on how to prepare for D Dimer test.
No specific preparation is necessary for this test.
The test results may be different depending on gender, age, health conditions, and other factors.
If the test results are above/more than the normal reference range, then it may indicate that there may be a chance for blood clots in the veins.
Based on the test results, your doctor may advise you appropriate medical treatments, lifestyle modifications, or further diagnostic tests, etc.
