ABI (Ankle-Brachial Index) systems are used to screen for peripheral artery disease (PAD) and assess lower extremity circulation through noninvasive vascular testing. Commonly utilized in cardiology, vascular, primary care, and specialty clinics, ABI machines provide fast, reliable measurements that help identify blood flow abnormalities and support early intervention. Lynn Medical offers ABI testing equipment, vascular diagnostic systems, and Doppler-based solutions from trusted manufacturers, backed by expert product support and service.
