Past research suggests that people without these specific markers might have a higher chance of developing heart disease, but the link to blood clots in veins is not well understood.\n\nThis study aims to answer:\n\n* Are certain Lewis antigen types more common in people with a history of VTE?\n* Do the Lewis antigen results relate to other known blood clot risk factors? Researchers will identify Lewis a and b antigens in 100 participants who attend the Haemostasis Disorders Clinic at the University Hospital of Larissa. All participants are people with a personal history of deep vein thrombosis, with or without an inherited or acquired tendency for blood clots.\n\nResearchers will also record other known risk factors for VTED for each participant.
