The UK Thrombosis Research Network (UK-TReN) is a not-for-profit network of medical professionals dedicated to delivering high quality, collaborative work in thrombosis across the UK.

The network is part of the international INVENT-VTE network, a network of academic research groups. This exists to promote international collaboration between academic research networks that conduct venous thromboembolism (VTE) related clinical research, and to enhance the profile, science, and impact of investigator-led VTE clinical research. INVENT seeks to enable research by its member groups, rather than to supplant the activities of individual member groups, and to promote a global culture of curiosity, scientific rigor and social responsibility in the conduct of VTE clinical research.
