What is Flow Cytometry?

Flow cytometry is a technology that provides rapid multiparametric analysis of single cells in solution. It is a laser-based method used to detect and measure the physical and chemical characteristics of a population of cells or particles.

Flow cytometers utilize lasers as light sources to produce scattered and fluorescent light, which is converted into electronic signals analyzed by a computer and written to a dataset. Some key aspects of flow cytometry include:

  • Applications: Flow cytometry has applications in various disciplines, such as immunology, virology, molecular biology, cancer biology, and infectious disease monitoring.
  • Sample preparation: Samples are prepared by incubating cells in tubes or microtiter plates with unlabeled or fluorophore-labeled antibodies or other markers.
  • Analysis: Flow cytometry allows for the simultaneous characterization of mixed populations of cells from various sources, such as blood, bone marrow, mucosal tissues, and solid tumors.
  • Multicolor flow cytometry: This technique analyzes multiple parameters on thousands of single cells, using fluorescent markers to characterize and define different cell types of interest.
  • Cell sorting: Although sometimes mistakenly called cell sorting, flow cytometers are analytical machines that do not perform cell sorting. Cell sorters use fluidics and fluorescence components similar to those in flow cytometers. Still, they can divert a specific population from a heterogeneous sample into a separate tube, typically based on specified fluorescence characteristics.

Flow cytometry is a powerful tool that has become increasingly sophisticated, with modern instruments offering increased detectable fluorescent parameters and improved data analysis capabilities.

Flow cytometry is a diagnostic tool used to analyze cells' or particles' chemical and physical characteristics, making it useful for various applications, including cancer diagnosis and monitoring. There are several reasons to get blood cells tested with flow cytometry:

  • Abnormal cell counts: Flow cytometry can help identify abnormal cell counts, which may suggest the presence of leukemia, lymphoma, or other diseases.
  • Cancer detection and diagnosis: Flow cytometry can detect the presence or absence of specific antigens in cells, aiding in diagnosing and monitoring certain types of cancers.
  • Disease progression and treatment response: Flow cytometry can help doctors determine the aggressiveness of a cancer, predict the effectiveness of a specific treatment, and monitor the relapse of a disease after treatment.
  • Immune cell analysis: Flow cytometry can assess the status of immune cells, helping to understand the body's immune response to infections or diseases.
  • DNA analysis: In some cases, flow cytometry can be used to analyze DNA, providing more information about specific genetic conditions.
  • Research and scientific applications: Flow cytometry is a valuable tool for researchers and pathologists to study the complexities of various biological systems and conditions.

Suppose you or your healthcare provider suspects that you may have a cancer or other condition that could benefit from flow cytometry testing. In that case, it is essential to discuss the procedure with your healthcare provider, who can explain the results and guide you on the next steps.

How is the Flow Cytometry Test used?

Flow cytometry is a versatile technology used in various ways, including diagnosing, classifying, and identifying specific DNA markers in cancer. It is also employed to detect, identify, and count specific cells and evaluate particular components within cells based on physical characteristics and tags called antigens on the cell surface.

The process involves suspending a sample of cells in a fluid and injecting them into a flow cytometer machine, where they are analyzed based on their reactions to laser light. Flow cytometry is commonly used to evaluate bone marrow, peripheral blood, and other body fluids, and it can be applied to a wide range of purposes, such as immunology, cancer diagnosis, and research.

Lab technicians or pathologists perform the test and typically require a sample of blood, bone marrow, tissue, or other body fluids. After the analysis, the results are interpreted by a healthcare provider, and the findings are discussed with the patient.

Multicolor Flow Cytometry

Multicolor flow cytometry is a powerful technique that allows the analysis of multiple targets on a single cell, providing rapid, multiparametric analysis of various cellular subpopulations of interest. This approach is precious for immune cell characterization and identifying abnormal cell subsets, such as cancer ones.

Using multiple colors and fluorescent markers, multicolor flow cytometry enables the simultaneous measurement of various parameters, making it possible to distinguish different cell types and detect minor or aberrant cell subsets within a mixed population.

For instance, a 9-color flow cytometry panel helps characterize different cell subpopulations, including myeloid cells, and detect minor/aberrant subsets within neoplastic samples, such as blood, lymph node nodes, and solid tumors. This capability makes multicolor flow cytometry valuable for immune cell profiling and comprehensive immune system studies in health and disease.

The power of Flow Cytometry in immunophenotyping

Flow cytometry is a powerful tool for immunophenotyping, which identifies and characterizes cells based on their surface markers or antigens. Immunophenotyping using flow cytometry has become the method of choice in identifying and sorting cells within complex populations, such as analyzing immune cells in a blood sample.

A given cell population can be identified and quantified by evaluating the unique repertoire of cell markers using several antibodies together, each coupled with a different fluorochrome. Many immunological cell markers are CD markers, and these are commonly used for detection in flow cytometry.

Flow cytometric immunophenotyping remains an indispensable tool for diagnosing, classifying, staging, and monitoring hematologic neoplasms. It is also used in clinical applications to diagnose disease or to monitor immune function.

Flow cytometry immunophenotyping can detect both normal cells and abnormal cells whose pattern of markers is typically seen in certain diseases, such as leukemia or lymphoma. The results may also be used to predict how aggressive the cancer will be and whether it will respond to treatment.

Choosing sample types for testing

Flow cytometry can analyze blood, bone marrow, tissue, and other body fluids. The choice of sample type depends on the specific diagnostic or research question being addressed.

For example, bone marrow testing is commonly used to diagnose and monitor bone marrow diseases, blood disorders, and certain types of cancer. Blood samples often detect biomarkers indicating cancer activity or examine various chemicals that can show how other body parts are functioning. Tissue samples may be used to identify cancer cells or to analyze DNA.

Flow cytometry can identify the type of cells in a sample, including the types of cancer cells, based on the presence or absence of certain protein markers. The most common use of flow cytometry is in identifying markers on cells, particularly in the immune system, called immunophenotyping.

Interpreting results

Interpreting flow cytometry results can be challenging, mainly when conducting multiparametric analyses that typically create extensive data. Correctly compensating and gating flow cytometry data requires a thorough understanding of how flow cytometry works.

The interpretation of flow cytometry results depends on the specific diagnostic or research question being addressed. However, some usual interpretations of flow cytometry results include:

  • Abnormal cell populations: The presence of abnormal cell populations may indicate the presence of certain conditions, such as cancer. For example, abnormal results could suggest the presence of acute lymphoblastic leukemia or chronic lymphocytic leukemia.
  • Marker expression: Flow cytometry can identify and quantify specific marker expressions on cell surfaces, which can help diagnose and classify various diseases.
  • Disease progression and treatment response: Flow cytometry can help determine the aggressiveness of a cancer, predict the effectiveness of a specific treatment, and monitor the relapse of a disease after treatment.
  • Immune cell analysis: Flow cytometry can assess the status of immune cells, helping to understand the body's immune response to infections or diseases.
  • Research applications: Flow cytometry is a valuable tool for researchers and pathologists to study the complexities of various biological systems and conditions.

It is important to note that flow cytometry interpretation requires a thorough understanding of the technique and the data generated. Therefore, the interpretation of flow cytometry results should be discussed with a healthcare provider or researcher to understand their implications and the next steps fully.
