Immunophenotyping is a type of flow cytometry used to diagnose leukemia or lymphoma. This test is usually done after abnormal results are seen on a complete blood count or WBC differential. With immunophenotyping, your results will state whether any abnormal cells are present and what types of cells they are.
Is flow cytometry used for immunophenotyping?
While this technique is still used, most immunophenotyping is now performed using flow cytometry. Flow cytometry is performed by processing a blood, bone marrow, tissue, or fluid sample and then adding specific antibodies that have been tagged with fluorescent markers.
How does flow cytometry diagnosis leukemia?
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 is flow cytometry immunophenotyping?
Immunophenotyping by flow cytometry is a laboratory method that detects the presence or absence of white blood cell (WBC) markers called antigens. These antigens are protein structures found on or within WBCs. Additionally, specific patterns of antigens are present on abnormal cells seen in leukemias and lymphomas.
Is flow cytometry accurate?
Abstract. Although the topic is somewhat contentious, fine-needle aspiration (FNA) is frequently used in conjunction with flow cytometry (FC) to evaluate lymphoid proliferations. We conclude that FC is an independently accurate ancillary test in the evaluation of FNA.
Is Immunophenotyping the same as flow cytometry?
Immunophenotyping is a very common flow cytometry test in which fluorophore-conjugated antibodies are used as probes for staining target cells with high avidity and affinity.
What does Leukemia Lymphoma panel by flow mean?
Leukemia and lymphoma analysis by flow cytometry aids in identifying the tumor lineage, which in most cases is identified as T cell, B cell, or myeloid. Lineage identification can provide a confirmatory diagnosis or differential diagnosis, prognosis, and treatment options.
What does leukemia Lymphoma panel by flow mean?
Can flow cytometry be wrong?
Detecting and characterizing leukocyte cell populations by flow cytometry requires that instruments are set optimally to clearly resolve positive from negative populations. This could easily be mistaken for an abnormal cell population.
Why is flow cytometry important?
The reason flow cytometry is so successful with heterogeneous cell populations is that it analyzes cells one at a time. It does this by using the properties of fluid dynamics. Flow cytometry data enables the user to understand each cell type and its properties on a deeper level.
What is immunophenotyping by flow cytometry?
Immunophenotyping by flow cytometry is a laboratory method that detects the presence or absence of white blood cell (WBC) markers called antigens. These antigens are protein structures found on or within WBCs.
Why is immunohistochemistry used to diagnose leukemia?
This approach, called immunohistochemistry, is used every day for some leukemia and lymphoma markers and other types of cancer. It may be because the markers of interest are not available for flow cytometry or because fresh cells or tissue are not available (a requirement for flow cytometry immunophenotyping).
What tests are used to diagnose leukemia and lymphoma?
These tests may suggest lymphoma or leukemia, but more information is generally needed to confirm a diagnosis and to identify a specific type of leukemia or lymphoma. Flow cytometry immunophenotyping may be performed on blood, bone marrow, or other samples to provide this additional information.
What is the role of immunophenotyping in the diagnosis of lymphoma?
While morphologic assessment of blood smears, bone marrow smears, and tissue sections remains the cornerstone of lymphoma and leukemia diagnosis and classification, immunophenotyping is a very valuable and important complementary tool.
