Quality control in clinical flow cytometry.
Immunophenotyping by flow cytometry is a robust and highly complex technology used in the enumeration and characterization of leukocytes, including normal lymphocyte subsets and hematologic neoplasms. Samples consist of peripheral blood and many times irreplaceable samples, such as bone marrow and fresh tissue. These samples are collected, transported, prepared, analyzed, and interpreted, resul...
متن کاملValidation and quality control of immunophenotyping in clinical flow cytometry.
Clinical flow cytometry has evolved from two-parameter quantitative assessment of peripheral blood lymphocytes to six-parameter qualitative evaluation of bone marrow for hematopathology. Leukemia and lymphoma immunophenotyping represent an extremely important complement to morphology in the diagnosis and monitoring of hematopoietic malignancies. The complexity of five- and six-parameter analyse...
متن کاملStandardization, Calibration, and Control in Flow Cytometry.
Because flow cytometers are designed to measure particle characteristics, particles are the most common materials used to calibrate, control, and standardize the instruments. Definitions and cautions are provided for common terms to alert the reader to critical distinctions in meaning. This unit presents extensive background on particle types and cautions and describes practical aspects of meth...
متن کاملFlow Cytometry as a Tool for Quality Control of Fluorescent Conjugates Used in Immunoassays
The use of antibodies in immunodiagnostic kits generally implies the conjugation of these proteins with other molecules such as chromophores or fluorochromes. The development of more sensitive quality control procedures than spectrophotometry is essential to assure the use of better fluorescent conjugates since the fluorescent conjugates are critical reagents for a variety of immunodiagnostic k...
متن کاملFlow Cytometry in Chronic Myelogenous Leukemia Blast Crisis
Background: Chronic myelogenous leukemia (CML) is a myeloproliferative disorder due to BCR-ABL1 translocation. Patients showing transformation into blast crisis (BC) have poorer treatment response and prognosis. Methods: A retrospective study was conducted in the department of Pathology, Maulana Azad Medical College, New Delhi, India, over a time period of 5 years (2014-2019) to evaluate the ...
