Having a predilection for the right side of the heart and accounting for 1% of all cardiac tumours, the difficulty in diagnosing the lesion, owing to the location and vague presenting symptoms and signs, often leads to delayed diagnosis and poor prognosis. This process is widely used to diagnose different types of lymphoma and leukemia by comparing normal cells and cancer cells. In fact, these two markers are not normally expressed together. Immunophenotypic characterization of the leukemic cells has been widely used as a tool for diagnosis, classification and prognosis of leukaemia. sharing sensitive information, make sure youre on a federal When cell counts drop below 5 cells/mcL, the immunophenotypic analysis may not be successful. As the number of abnormal cells increases in the bone marrow, they may crowd out and inhibit the production of normal white blood cells, red blood cells, and platelets, and eventually abnormal cells may also be released into the blood.
