Flow Cytometer: The Need of Modern Hematology Laboratory

Abstract

Indeed, laboratory diagnosis is rapidly changing from what it was in the past to the present. Nowadays, flow cytometer (FCM) has become a novel introduction to the modern diagnostic technique, mainly in the field of hematology. In case of acute leukemia, peripheral blood, bone marrow examination, cytochemistry and immunohistochemistry for differentiation of myeloid or lymphoid lineage is required, which is feasible by flow cytometry. It has dramatically improved the diagnostic efficiency and reduced the duration of sampling along with better diagnostic outcomes as well as provided efficient therapeutic monitoring of any drug or drug regimen. It has also opened some more sensitive therapeutic plans, like monitoring “Minimal residual disease (MRD)”, which is not possible without FCM. Detection of MRD has led to improved overall survival of patients. It has also opened up huge opportunities for research, which has become an important part of academic curriculum nowadays. Considering the importance and absolute necessity for better outcomes in hematology, the knowledge of basic principle of FCM becomes indispensable. Here, we try to elucidate the elementary components of this technique and also highlight its uses.
