Standardization of immunophenotyping requires careful attention to reagents, sample handling, instrument setup, and data analysis, and is essential for successful cross-study and cross-center comparison of data. Experts developed five standardized, eight-color panels for identification of major immune cell subsets in peripheral blood. These were produced as pre-configured, lyophilized, reagents...

INTRODUCTION The diagnosis of systemic mastocytosis (SM) is based on a combination of major and minor criteria. Flow cytometric detection of aberrant expression of CD2 and/or CD25 on CD117-positive mast cells is one of the minor criteria used. In the present study we examined the sensitivity and specificity of mast cell immunophenotyping in the diagnosis of SM. MATERIAL AND METHODS Patients w...

abstract background leukemia is one of the most common tumors in children and it is divided up into two main groups acute and chronic leukemia. the acute leukemia is more prevalent than chronic in children. generally acute type is included acute lymphoid leukemia (all) and acute myeloid leukemia (aml). in this study, patients with leukemia who were admitted in talghani hospital of gorgan were e...

acute lymphoblastic leukemia (all) is a malignant disorder of lymphoid precursor cells, which could be classified according to morphological and cytochemical methods as well as immunophenotyping. twenty patients with all, who had been referred to the children's medical center hospital, during the year 2007, were enrolled in this study in order to evaluate the morphologic and immunophenotypic pr...

BACKGROUND AND OBJECTIVE The diagnosis of acute leukemias (AL) requires a multiparametric approach in order to apply risk-adapted therapeutic protocols and appreciate the potential outcome of any given patient. Blast cells immunophenotyping is a key test in this issue, yet the information provided by immunophenotyping has become staggering, and it may be difficult to identify relevant character...
