WebFlow cytometry gating “Gating” is a basic principle of flow cytometry. It refers to the process of identification and refinement of a specific cellular population. To do this, the pathologist can select an area on the computer-generated chart. This will tell the flow cytometry machine which cells to keep analyzing and which ones to stop ... 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.
