Our patient has a confirmed left sided DVT. Prior to initiation of anticoagulation a clotting screen is performed. It shows:

• PT 12s (11-14)
• APTT 49s (35-40)
• Fibrinogen 5.5g/L (1.5-4)
• d-dimer 990ng/mL (<500)

Questions

• How do you interpret the results?
• What investigation would you next perform?
