Frequently Asked Questions
What does a D-Dimer test measure?
D-Dimer measures fragments produced when a blood clot is broken down by plasmin. Elevated levels suggest active clot formation and breakdown in the body, commonly used to rule out DVT and pulmonary embolism.
Is fasting required for D-Dimer test?
No, fasting is not required. The test can be performed on a non-fasting sample.
What sample is needed for this test?
The sample required is 3 mL of citrated plasma collected in a light blue top tube. Proper filling to the mark is essential for accurate citrate-to-blood ratio.
How is a D-Dimer result interpreted?
A negative result below the lab cutoff (typically <0.5 μg/mL) effectively rules out thromboembolism in low-risk patients. Elevated levels can occur in DVT, PE, pregnancy, infection, inflammation, post-surgery, and malignancy, requiring clinical correlation.
How long does it take to get D-Dimer results?
Results are typically available within 24 hours. Verified PDF reports can be accessed via www.drpatholab.in or WhatsApp/Email.
Can medications affect D-Dimer levels?
Yes, anticoagulant therapy such as heparin or warfarin can influence D-Dimer values. Always inform your doctor about current medications before testing.
