In this episode, Kevin looks at common questions around non-visible haematuria (NVH) – the condition formerly known as microscopic haematuria. Should we be screening for NVH? What follow-up investigations should we do for people with asymptomatic NVH? Should we change our approach for patients taking aspirin, warfarin or direct-acting oral anticoagulants (DOACs)? Finally, who should we refer and how urgently?
