What D-Dimer measures

A fragment released when a blood clot breaks down, used mainly to rule out clots in veins and lungs.

What a high D-Dimer means, and common causes

A raised D-dimer means a clot has formed and broken down somewhere. It is useful mainly for ruling clots out, because many harmless things raise it.

Common causes: Deep vein thrombosis and pulmonary embolism, but also recent surgery, infection, pregnancy, cancer, liver disease and simply older age.

What a low D-Dimer means, and common causes

A low or normal D-dimer makes a significant clot very unlikely, which is the main value of the test.

Common causes: Not applicable. A normal result is the reassuring one.

Frequently asked questions

Usually under 0.5 mcg/mL FEU, though the cut-off rises with age.

Not necessarily. It is far better at ruling clots out than confirming them. A raised value usually leads to imaging such as a Doppler scan or CT.
