A new test developed by the University of Surrey could help spot poor blood flow in the legs and feet much earlier.

The ultrasound method, called eTBI, is said to be more accurate and reliable than the current test, especially for people with diabetes.

Poor circulation, known as peripheral artery disease, can lead to pain, ulcers, and even amputation if not caught early.

Lead researcher Professor Christian Heiss says the new test could help doctors treat the condition sooner and stop it from getting worse.
