 1. Deep venous thrombosis is a common suspected medical condition. If it cannot be excluded clinically and using D-dimer, ultrasound examination is required. An option for traditional radiologist-performed ultrasound is a 2-point compression ultrasound 2-CUS. The safety of this technique is proven. However there does not exist any data on costs comparing traditional and 2-CUS pathways in primary health care. This study will evaluate the total cost of both pathways by conducting a cost-minimization analysis. It will also study the effect of a simple ultrasound education on the referrals to hospital due to suspected DVT. T
