WebThe basic principle of flow cytometry is the passage of cells in single file in front of a laser so they can be detected, counted and sorted. Cell components are fluorescently labelled and then excited by the laser to emit light at varying wavelengths. The fluorescence can then be measured to determine the amount and type of ... WebThe precision of the method is mediocre (CV: 30–40%), and a systematic overestimation of the extent of the FMH has been shown with this technique (reference 2). Screening for FMH by flow cytometry is well-correlated with the reference cytochemical technique, but it is more precise and more reproducible.
