A thrombus is a blood clot that forms in a blood vessel. Predisposition for thrombosis is hereditary to a high degree (approx. 50%). In case of relatives with thrombosis, it is advisable to test whether your risk is increased. This is particularly useful if you have a sedentary occupation, frequently take long-distance airplane flights, or plan to become pregnant. Pregnancy increases risk for thrombosis by 4-fold owing to hormonal changes. Genetic risk factors further increase likelihood for thrombosis during pregnancy.
The result informs you whether you have an increased genetic risk for thrombosis. If this applies you can take appropriate preventive measures.
