Urine test could help clinicians spot blood clots in at-risk patients

(American Thoracic Society) A new study by researchers from California and Canada indicates a simple urine test can indicate the presence of venous thromboembolism, a blood clot that has broken free from its point of origin and which travels through the bloodstream, eventually lodging in a vein. The test evaluates the levels of fibrinopeptide B, a small peptide that's released when a thrombosis forms and which is removed from the body through urine.
