What is D-Dimer (D-Dimer)?

D-Dimer is measured as part of a coagulation panel. Your D-Dimer is normal, which makes an active blood clot unlikely.

What does a high D-Dimer mean?

Your D-Dimer is elevated. This is non-specific — it rises with clots but also with infection, inflammation, pregnancy, recent surgery, and age. A raised D-Dimer usually prompts further imaging rather than being diagnostic on its own.

Understand your whole report, not just one number

A single value rarely tells the full story — D-Dimer is best read alongside the rest of your panel. Paste your values or upload your report and get a plain-English explanation of every marker, with the important results flagged.
