Pathology - Anti-coagulant monitoring service

The DAWN Anticoagulant Service provides a maintenance warfarin dosing service to a number of GP practices across Worcestershire.

The DAWN Anticoagulant Service is open from Monday to Friday from 9.00am to 5.30pm

INR blood samples are taken at the GP surgeries and then sent to the hospital for analysis. Results are reported within 24 hours and are either phoned or posted to patients. All high INRs (greater than 5) are dosed on the day the sample was taken, by the DAWN dosing team. After 5.30pm, INRs of 5 or above are phoned through by the laboratory staff to the Out Of Hours GP service.
