D dimer: D dimer cant diagnose a blood clot but it is a blood test that can be helpful in diagnosing or ruling out a blood clot. Now days most blood clots are diagnosed with ultrasound.

Blood tests for clot: There are no specific blood tests that will be definitive to prove a clot exists. Ultrasound, CT andMR are the diagnostic modalities to prove a clot. D-dimer is a blood test that can be used to identify clot formation but it is very non specific. If negative there is good evidence that a clot does not exist but d-dimer can be positive for many reasons not related to a clot.
A 48-year-old female asked:
Are blood tests required if DVT is suspected?

Not required: But elevated levels of d dimers strongly supports the diagnosis
DVT is diagnosed with ultrasound in the leg
In abdomen ct scan is typically needed
