What is Flow cytometric analysis?
Flow cytometry is a laser-based technique used to detect and analyze the chemical and physical characteristics of cells or particles. It is most commonly used to evaluate bone marrow, peripheral blood and other fluids in your body. Cancer Answer Line 866.223.8100.
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.
What are the advantages of using flow cytometric analysis?
Advantages of the automated flow cytometric techniques are that results can be obtained in short time intervals, the frequency of MN and the DNA distribution of MN can be measured simultaneously and flow sorting can be used for a further analysis of MN using other techniques.
What is immunophenotyping blood test used for?
Immunophenotyping is used primarily to help diagnose and classify the blood cell cancers, leukemias and lymphomas, and to help guide their treatment.
What are the 3 main components of flow cytometry?
The three main components of a flow cytometer are the fluidics, optics, and electronics (Figure 1). The fluidics system of a flow cytometer is responsible for transporting sample from the sample tube to the flow cell.
How much does a flow cytometry test cost?
The cost per test for Cyflow is between $3.00 and $5.00, whereas that of Dynabead ranges from $12.00 to $22.00 and other flow cytometry techniques are as high as $30.00 to $100.00 per test (1, 6). Therefore, Cyflow is three- to fourfold more cost-effective.

How long does it take to get flow cytometry results?
Results are submitted for hematopathologist review and interpretation. The typical turn-around time for our diagnostic flow cytometry results is within 1-3 days.
What are limitations of flow cytometry?
Limitations to flow cytometry include the facts that the laser can only analyze one cell at a time, cells must be in suspension to be analyzed (thereby restricting the analysis of tissue), highly trained operators are required, and cells must be viable to be analyzed.
What are the application of flow cytometry?
The most common application performed on the cytometer is immunophenotyping. This technique identifies and quantifies populations of cells in a heterogeneous sample – usually blood, bone marrow or lymph. These cell subsets are measured by labeling population-specific proteins with a fluorescent tag on the cell surface.
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 the basic principle of flow cytometry?
Flow cytometry (FCM) is a technique which enables rapid analysis of statistically significant number of cells at single cell level. The main principle of this technique is based on scattering of light and emission of fluorescence which occur when a laser beam hits the cells moving in a directed fluid stream.
How long does it take to get results from a flow cytometry test?
How accurate is flow cytometry?
The overall diagnostic accuracy of FC was 88.4% (95% CI, 85.2%–91.1%) with a sensitivity of 85.8% and specificity of 92.9% Table 1. When a limited panel of antibodies (<6) was used, the diagnostic accuracy of FC declined to 81.8%, compared with 90.1% when a more extensive antibody panel was used (P = . 039).
What are the indications for flow cytometry?
Monoclonal antibodies have been used as immunotherapeutic agents against a variety of diseases such as leukemia, lymphoma, breast cancer, Crohn’s disease and rheumatoid arthritis.

What are three possible clinical uses for flow cytometry?
1 This article discusses current clinical uses of flow cytometry, emphasizing immunopheno- typing, reticulocyte and reticulated platelet enu- meration, multiple drug resistance assays, cell function assays, and apoptosis.

Can flow cytometry detect lymphoma?
Flow cytometry is rapid and appears to be virtually diagnostic of non-Hodgkin’s lymphoma when a majority of cells are B cells with an abnormal kappa/lambda ratio (> 4.0 or < 0.25). Nonhematologic malignancy can be suspected if less than 75 percent of the cells show CD45 (common leukocyte antigen).
What are the applications of flow cytometry?
What are the warning signs of lymphoma?
Signs and symptoms of lymphoma may include:
- Painless swelling of lymph nodes in your neck, armpits or groin.
- Persistent fatigue.
- Fever.
- Night sweats.
- Shortness of breath.
- Unexplained weight loss.
- Itchy skin.
What is the most common early symptom of lymphoma?
The best way to find lymphoma early is to pay attention to possible signs and symptoms. One of the most common symptoms is enlargement of one or more lymph nodes, causing a lump or bump under the skin which is usually not painful. This is most often on the side of the neck, in the armpit, or in the groin.
Where does lymphoma start in the body?
Lymphomas can start anywhere in the body where lymph tissue is found. The major sites of lymph tissue are: Lymph nodes: Lymph nodes are bean-sized collections of lymphocytes and other immune system cells throughout the body, including inside the chest, abdomen, and pelvis.
Where do you itch with lymphoma?
Cytokines can irritate nerve endings in the skin, which can in turn cause persistent itching. Many individuals experience this itchiness in their hands, lower legs or feet, while others feel it throughout their entire body. Patients often report that the itching tends to worsen while they are lying in bed at night.
