Reticulocyte counting using flow cytometry.
A flow cytometric method for the quantitation of reticulocytes was refined for routine laboratory use. Blood (2 microliters) is added to 2 ml of 0.4 microM thiazole orange in phosphate buffered saline, incubated at room temperature for 90 minutes, and analysed on a Coulter EPICS Profile flow cytometer, with gating for red cells on the basis of forward and right angled light scatter. Blood (2 mi...
متن کاملReticulocyte counting by flow cytometry. A comparison with manual methods.
The reticulocyte count (RC) is a key diagnostic test in the evaluation, classification, and response to therapy of anemia. The RC, as determined by manual methods, has a frustrating inherent imprecision owing to its binomial counting statistics (i.e., low counts/low precision) and inaccuracy because of inter- and intraobserver variability as to what indeed is a reticulocyte. Fluorescent activat...
متن کاملOptimized Method for Reticulocyte Counting: Simple, Accurate, and Comparable to Flow Cytometry
Background: Reticulocytes are immature red blood cells with RNA, spending the final stages of their maturation in the peripheral blood. The number of reticulocytes in the peripheral blood is the salient evidence of the effectiveness of bone marrow to produce red blood cells. Currently, reticulocyte count is done manually or automatically in clinical laboratories. Difficulties and limitations of...
متن کاملDetection of borreliacidal antibody by using acridine orange and flow cytometry.
Borreliacidal antibody has been shown to be important for the serodiagnosis of Lyme disease and determination of immune status. Our results show that borreliacidal antibody can be rapidly and accurately detected by flow cytometry. Acridine orange was added to normal and immune sera containing Borrelia burgdorferi organisms in the presence and absence of complement prior to data acquisition by f...
متن کاملSupravital Blood Studies, Using Acridine Orange Fluorescence
LTHOUGH FLUORESCENCE microscopy had its beginnings over half a century ago, it has only recently gained widespread usage as a research tool, and practical applications have yet to be fully exploited. Blood has been one of the tissues most extensively studied by fluorochroming,’ but few reports have been published in English. In addition, the previously reported saline dilution technics for supr...
