Introduction and Target: The number of thrombocytes is defined as 150,000/mm3 of six thrombocytopens. Isolated trombocytopenia is normal in other series (eritrosite and leukocytes) and is characterized only by a low trombocytes value. In this study, we aimed at evaluating the etiological diagnosis, clinical characteristics and blood parameters of patients who apply to the hematological clinic due to isolated thrombocytopenia. Method and Requirements: From October 2016 to January 2018 the files of patients traced due to thrombocytopenia were scaned backward in our clinic. 301 patients identified with isolated thrombocytopenia were included in the study. According to pathophysical ethology, isolated trombocytophen was classified. Full blood count values for other diseases that lead to primary immune trombocytopenia (ITP) and isolated trombocytopenia were compared. 202 of the patients were female and 99 male. In 173 patients, increased blood cell consumption, 45 patients with false trombocytopenia, 27 patients with trombocyt sectation (hypersplenism) and 3 patients with reduced blood cell production were diagnosed. In 54 patients, the thrombocytes value was between 100,000-150,000 / mm3 and there was no pathology to explain this condition. Primary ITP was the most commonly detected disease in patients with isolated thrombocytopenia (35.8%) and the number of thrombocytes in these patients was significantly lower than in other diseases that caused isolated thrombocytopenia. The most common cause of isolated trombocytopenin in our study was primary ITP, the second most common cause of false trombocytopenin. Other causes related to the drug and infection, gestational trombocytopenia, collagen vascular diseases and hyperplenism were found. Trombocytopenia is a laboratory discovery and can be associated with a variety of diseases. There is no specific test to identify isolated trombocytopenia. First of all, the distinction between true and false trombocytopenia and peripheral spread should be made. Then the diagnosis should be achieved through comprehensive history, physical examination and other laboratory tests.
