Abbott FreeStyle Libre 3 glucose monitoring system

FreeStyle Libre 3 is a Continuous Glucose Monitoring (CGM) system produced by Abbott Diabetes Care. The brand was originally developed by TheraSense, a company founded in California, USA, which was acquired by Abbott Laboratories in 2004.

Abbott Laboratories, the ultimate owner, is a multinational medical devices and healthcare company headquartered in Chicago, Illinois. While the brand is American, the specialized sensors for the FreeStyle Libre system are primarily manufactured in Witney, Oxfordshire, in the United Kingdom, which serves as one of Abbott's largest production sites for diabetes technology. The product is distributed globally through various local Abbott subsidiaries.
