Unfortunately, there is no generally accepted world-wide criterion of difference definitively diagnostic although a volume of difference of 200 ml between limbs or a 4 cm (at a single measurement site or set intervals along the limb) is often used. Recently the technique of bioimpedance measurement (a method that measures the amount of fluid in a limb) has been shown to have greater sensitivity than these existing methods and holds promise as a simple diagnostic and screening tool. Impedance analysers specifically designed for this purpose are now commercially available.
Similarly assessment and monitoring of<unk>  progression or its response to treatment is usually based on the changes in volume, circumference or impedance over time.
