D-Dimer Test In Mumbai - Price & Details

A D-dimer test is a blood test used to help assess the likelihood of a serious blood clotting disorder.

When a blood vessel is injured, the body initiates a natural clotting process known as hemostasis to prevent excessive bleeding. During this process, a protein called fibrin forms a mesh that stabilises the blood clot. Once healing is complete, the clot is gradually broken down, releasing several by-products into the bloodstream, including the D-dimer.

Under normal circumstances, D-dimer levels remain low. However, elevated levels may occur when there is significant clot formation and breakdown within the body, such as in conditions like deep vein thrombosis (DVT), where a clot forms in a deep vein, most commonly in the legs.

The D-dimer test may also be referred to as a fibrin degradation fragment test or fragment D-dimer test.

A D-dimer test is commonly used to help rule out conditions associated with abnormal blood clotting, including:

• Deep vein thrombosis (DVT): Symptoms may include leg pain, swelling, redness, or warmth.
• Pulmonary embolism (PE): Symptoms can include shortness of breath, chest pain, rapid heartbeat, or coughing.
• Stroke: Warning signs include sudden weakness or numbness, difficulty speaking, dizziness, vision changes, or loss of coordination.
• Disseminated intravascular coagulation (DIC): May cause unusual bleeding, bruising, chest pain, or swelling and pain in the limbs.

• The test may also be used to assess clotting abnormalities following bites from certain venomous snakes, particularly vipers.

Because these conditions can be medical emergencies, prompt medical attention is recommended if symptoms occur.

• People who are being treated with blood thinners (anticoagulant medicines) may be advised to take this test to check how much longer they need to continue the treatment. 
• The test may also be used to monitor treatment response in patients with DIC, as decreasing D-dimer levels can indicate improvement.

• The D-dimer test is not typically performed on a regular schedule. Your doctor may prescribe this test when there is a suspicion of a blood clotting disorder or to assess the outcome of treatment or the progression of the condition in patients with known clotting conditions.

• Deep vein thrombosis (DVT)
• Pulmonary embolism (PE)
• Disseminated intravascular coagulation (DIC)
• Stroke
• Snake bites of certain snakes
• Assessing progress in patients undergoing treatment for clotting disorders

The D-dimer test does not require any specific preparation unless other tests are being done at the same time.

What to Expect Before the Test

• This test can be done at any time of the day, irrespective of fasting status.

What to Expect During the Sample Collection

• A D-dimer test usually takes just a few minutes. You can sit or lie down while the phlebotomist finds the vein they wish to use and sterilises the skin over it. They will use a thin needle to take a small amount of blood in a test tube. Then they will bandage the area.
• Your blood sample will be taken to the lab for testing.

What to Expect After the Test

• A slight pain or a sting may be felt when the needle is inserted. Mild throbbing at the site may also be felt after the blood is drawn.

Note: If you notice anything unusual at the puncture site, such as persistent bleeding, a rash, or pain, consult your healthcare provider.

The D-dimer test measures a single key parameter:

• D-dimer level - measured in μg/mL FEU or ng/mL (nanograms per millilitre).

Important note: Normal D-dimer ranges vary between laboratories and assay methods. Age-adjusted thresholds (age x 10 ng/mL for patients above 50 years) are used in some clinical guidelines. Pregnancy is associated with progressively rising D-dimer throughout all trimesters. Always refer to the ranges on your specific report and consult your doctor for interpretation.

Potential Risks and Complications

You may feel a pinch or a sting when the needle is inserted. The risks from a blood draw test are minor. But rarely, you could have: 

• Multiple needle sticks from your provider looking for a vein 
• Heavy bleeding
• Dizziness or fainting
• A bruise from blood collecting under the skin
• Infection

Understanding D-Dimer Test Limitations

• In individuals who have a high chance of a clot, this test may not help with diagnosis. Some conditions that may raise your chances of having a clot are clotting diseases that you are born with, major surgery, major injury, such as a broken leg, long periods of sitting or lying down, pregnancy or the postpartum period, and some cancers.
• If your doctor knows that your odds of having a clot are higher, they may skip the D-dimer in favour of other imaging tests to make a diagnosis.

• Sometimes, a high D-dimer level may occur without the presence of a blood clot. Older age (more than 80 years old), pregnancy, infection, sepsis, liver disease, certain cancers, heart disease, high cholesterol, recent injury or surgery, an autoimmune disorder, and rheumatoid arthritis may cause increased levels of D-dimer.
• Certain medications can alter D-dimer results. They will usually cause a false-negative. These drugs include antiplatelet drugs such as aspirin, clopidogrel, prasugrel or ticagrelor and drugs such as statins taken for high cholesterol.

• The test can only determine the presence of abnormal clotting in the body, not determine the location or size of a blood clot.

Note: Always consult a doctor before ordering or interpreting a D-dimer test. Never make treatment decisions based on D-dimer alone.
