DVT Investigations RFL


Direct access vascular studies service for ambulatory patients with suspected acute deep vein thrombosis (DVT).

If the patient is found to have an acute DVT, they will be sent to A&E or haematology for a same day follow-up.

The results are emailed to the practice by the secure email address supplied on the request form. Should the patient not be found to have acute DVT, the GP retains responsibility for follow-up. 

Eligibility criteria


  • see inclusion criteria on request form (includes modified Wells clinical score) 


  • patients with signs or symptoms of COVID-19 and currently in self-isolation whether through test positivity, symptoms or contact with others. Patients should be screened for these prior to referral.
  • not registered with a GP, or not ambulatory – the service cannot accommodate them via the direct access referral route. Consider sending ineligible patients to local ED.
