What test for lower extremities circulation problems?

The most common test for assessing lower extremity circulation problems is the Ankle-Brachial Index (ABI). This non-invasive test compares the blood pressure in the patient's ankle with the blood pressure in the arm to evaluate blood flow. A low ABI value can indicate peripheral artery disease (PAD) or other circulatory issues. Additional tests, such as Doppler ultrasound or angiography, may also be used for further evaluation.
