How is flow cytometry performed?
Flow cytometers take in a suspension of monodisperse single, unclumped cells and run them one at a time (single file) past a laser beam where each cell passes through the laser beam, scattered and fluorescent light and are then counted and sorted or further characterized.
How long does a flow cytometry test take?
The test takes approximately three hours and consists of staining the cells, acquiring the cells on a flow cytometer, and then having a skilled technologist analyze the results that have been saved to a computer file.
What is flow cytometry and how does it work?
Flow cytometry is a technology that rapidly analyzes single cells or particles as they flow past single or multiple lasers while suspended in a buffered salt-based solution. Each particle is analyzed for visible light scatter and one or multiple fluorescence parameters. Light scatter is independent of fluorescence.
Where is flow cytometry performed?
bone marrow
Flow cytometry immunophenotyping may be performed on blood, bone marrow, or other samples to provide this additional information. It can detect normal cells as well as abnormal cells whose pattern of markers are typically seen with specific types of leukemia and lymphoma.
What does a flow cytometry test for?
Flow cytometry can identify the type of cells in a blood or bone marrow sample, including the types of cancer cells. It detects types of cancer cells based on either the presence or the absence of certain protein markers (antigens) on a cell’s surface.
What does a flow cytometry test show?
How accurate is flow cytometry?
The diagnostic accuracy of FC was 88.4%, sensitivity was 85.8%, and specificity was 92.9%. In addition, FC accuracy for classes of non-Hodgkin lymphoma was assessed. We conclude that FC is an independently accurate ancillary test in the evaluation of FNA.
What is a flow cytometry used for?
Flow cytometry is a laboratory method used to detect, identify, and count specific cells. This method can also identify particular components within cells. This information is based on physical characteristics and/or markers called antigens on the cell surface or within cells that are unique to that cell type.
What are the application of flow cytometry?
It has broad application in medicine especially in transplantation, hematology, tumor immunology and chemotherapy, prenatal diagnosis, genetics and sperm sorting for sex preselection. Flow cytometry is widely applied to detect sperm cells abnormality associated with DNA fragmentation in male fertility assays.
