Task: Answer Verification
Input (English): Question: Do normal D-dimer levels exclude thrombotic complications in trauma patients?
Answer: In the early postinjury phase, a negative d-dimer test does not exclude DVT or PE. However, the negative predictive value of a D-dimer test after the first 4 days from admission rose to 100%. Patients with clinical signs and symptoms of DVT or PE in the immediate postinjury phase should undergo further screening to exclude thromboembolic complications.
Output (English): no
