Да это гормоны щитовидки, у нас их проверыют для вявления "клоттинг". Кстати все мои подруги которые немогли забеременеть из-за гемостаза имели проблемы с щитовиткои.•Thyroid disorders, which alter the balance of clotting factors and anticoagulants and can increase the risk of thrombosis. Hyperthyroidism (high thyroid function) increases the risk of thrombosis due to disruption of the clotting process, such as increased production of clotting factors, increased thrombin activity, and reduced rate of fibrinolysis (clot breakdown) (Erem 2011). Hyperthyroidism also can increase blood volume, which can lead to high blood pressure and cardiac arrhythmias, both of which are risk factors for thrombosis (Franchini 2006). In hyperthyroid patients, the incidence of arterial thrombosis, especially cerebral thrombosis, is between 8 and 10% (Burggraaf 2001). Hypothyroidism (low thyroid function) also increases the risk of thrombosis. Hypothyroid patients cannot clear clotting factors from the blood as quickly, have elevated levels of fibrinogen, and have reduced rates of fibrinolysis (Erem 2003).
