Tongue camera could spot bleeding danger in rare blood disorders

This study is testing a new, non-invasive method to predict bleeding risk in people with von Willebrand disease and other inherited bleeding disorders. Researchers will use a special microscope to look at tiny blood vessels under the tongue. The goal is to see if the density of these vessels can identify who is at higher risk for serious bleeding. The study involves 400 adults and does not offer a treatment, but aims to improve future care.
