If a DVT is suspected, a blood test known as the
D-dimer can be performed. This detects fibrin breakdown
that is present in the blood post thrombus formation. The
test is used for negative predictability only, meaning that a
negative result indicates no DVT, while a positive will result
in further tests being carried out. If a positive D-dimer occurs
the individual may then be sent for an ultrasound—the most
appropriate and accurate test for diagnosing a DVT.
