Initial laboratory studies showed severe thrombocytopenia of 3x10<sup>9</sup>/L (150-400x10<sup>9</sup>/L) with no abnormal platelets or schistocytes seen on peripheral blood smear, with normal prothrombin time/international normalized ratio (PT/INR), partial thromboplastin time (PTT) and fibrinogen levels. Here, F2 is linked to Thrombocytopenia.
