What besides a blood clot can cause a high d dimer test?

A high D-dimer test can be caused by various conditions besides blood clots, including recent surgery, trauma, or infection. Other factors like inflammation, liver disease, and certain cancers may also lead to elevated D-dimer levels. Additionally, conditions such as pregnancy can contribute to increased D-dimer levels. It's important to interpret the results in conjunction with clinical findings and other diagnostic tests.
