Flow cytometry analysis shows less than 2% of the cells from the sample expressing lymphocytic markers (CD45, and CD5 or CD20). Cell sorting involves using a flow cytometer with cell sorting capability to interrogate cells stained with fluorescent markers, classifying them into groups, and then physically separate the groups into test tubes or multi-well plates. The detection rate of CSF involvement in hematological malignancies is up to 86% higher in flow cytometry than in conventional cytomorphological analysis (6, 14, 42-48; Table 2). Figure 1. See #2 below. BTW, this sounds easier than it is. After review of the clinical history and morphology, a panel of markers is selected for each case by a board-certified hematopathologist. Typical samples include everything from a cell line expressing Green Fluorescent Protein to heterogeneous cell populations harvested from tissues. The most critical requirement for efficient and effective flow cytometry analysis is that the sample be a single-cell suspension. This helps ensure that every cell is analyzed independently. One of the fundamentals of flow cytometry is the ability to measure the properties of individual particles . Prepare your cell suspensions for Flow Cytometry.

BioAffinity's CyPath Lung uses flow cytometry to analyze the cells in a person's sputum, or phlegm, to find cancer cells that have sloughed off a lung tumor during collection of the sample. The risks associated with flow cytometry are limited the risks associated with sample collection. Therefore, the risks depend on the type of sample being used. A blood sample or semen sample is relatively easy to collect safely. In contrast, a bone marrow sample or tissue sample is more difficult, and carries some additional risks. Flow Cytometry.
