I have raised d-dimer levels. could i have a pulmery embolism?

Not necssarily: D dimer elevation does not mean that you have a blood clot or a pulmonary embolism.The ddimer can be elevated for many reasons.

Depends: D-dimer is a test that tells you that there is a new clot in your body but does not tell you where . Pulmonary embolism needs a ct angiogram of the pulmonary artery to diagnose it. A negative d dimer has an excellent sensitivity to rule out pulmonary embolus . A positive test is not very helpful.
