D-Dimer
A marker of active clot formation and breakdown, used mainly to rule out dangerous blood clots.
Consider this test if:
- Sudden leg swelling, calf pain, or unexplained shortness of breath that warrants ruling out a clot
- Working up possible DVT or PE alongside a clinical risk assessment
- Recovering from a known clot and monitoring resolution with your clinician
- Evaluating unexplained signs of abnormal clotting activity
- HSA/FSA eligible
- Typical results in 1 day · Reviewed by a real clinician
- Drawn at a CLIA/CAP-accredited lab near you ·
Pre-test considerations
No fasting required. The blood draw must be collected and handled correctly for an accurate result, so timing matters more than diet. Recent surgery, trauma, infection, active inflammation, pregnancy, and older age all raise D-dimer and should be considered when reading an elevated value.

What this test is for
D-dimer is a fragment left behind when the body breaks down a fibrin clot, so its level rises whenever clotting and clot breakdown are active. Its main clinical use is exclusion: in someone with a low or moderate clinical suspicion of deep vein thrombosis (DVT) or pulmonary embolism (PE), a result below the threshold makes a clot very unlikely and can avoid further imaging. An elevated result is far less specific, because levels also climb with infection, inflammation, recent surgery or trauma, cancer, pregnancy, and increasing age, so a high value points to further testing rather than a diagnosis. It is most informative when paired with a validated pretest probability assessment, and a clot present for more than a week can sometimes give a normal value.

Frequently asked questions
View all FAQsHow does pricing work?
Every test shows the member price next to the standard non-member price, so you can see what membership saves you. The member price is our cost — covering the lab and what it takes to run the service — never a profit on the test itself; Mito makes its money on the $9 membership, not on marking up your tests. Membership is $9/mo, and you still pay the lab’s order fee. Prices are itemized before you pay, with no hidden fees.
Where do I get tested?
Choose a partner lab (Quest, Labcorp, or BioReference) at checkout. If your cart spans multiple tests, we consolidate the whole order onto a single lab so you only make one visit.
Is this eligible for HSA/FSA?
Yes. This test is HSA/FSA eligible, and you can pay with your HSA/FSA card at checkout.
When will I get my results?
Your results post to your dashboard once your lab completes them, then a clinician reviews them and your full analysis and personalized action plan (with clear next steps) follow. Turnaround varies by test: specialty assays and at-home kits take longer, and each test shows its expected turnaround before you buy.
Do I need a doctor’s order?
No. Mito provides the lab order for you, so you can book and get tested without a separate doctor visit.
