Morphology: Specialists, such as pathologists, hematologists, and oncologists, may look at a person’s bone marrow sample under a microscope to check cell size and structure, which can aid in classifying leukemias.Numerous smudge cells have links to leukemia. Peripheral blood smear: Looks for the remains of abnormal white blood cells typically found in the lymphatic system, called smudge cells or basket cells, which have no clear cell boundaries.CBC with differential: Measures the number of blood cells, including red blood cells, platelets, and various white blood cells.While signs and symptoms may already suggest CLL, doctors will usually request more than flow cytometry. They will typically check for swollen lymph nodes, tenderness in the abdomen, and other symptoms, including: They then run the sample through a laser or multiple lasers one at a time.ĭetectors read the scattered and fluorescent light that appears once cells pass through laser beams and convert the signals into data for a doctor or healthcare professional to interpret.Ī doctor will first perform a thorough physical examination and look at a person’s medical history if they have symptoms of CLL. After preparation, the sample dilutes in a salt-based solution that resists pH changes, and lab technicians place the diluted sample on a narrow tube. They treat samples with biological stains, known as fluorochromes, highlighting specific cellular markers when “excited” by lasers. Flow cytometry detects the presence of these antigens on a cell’s surface.īefore testing, a medical practitioner obtains a sample of a person’s blood or bone marrow. the type and amount of specific surface receptorsĮach cell has specific groupings of antigens that determine the cell it came from - the cell lineage - and how far it is along the process of changing from one cell type to another, which healthcare professionals refer to as cellular differentiation.Flow cytometers are instruments that determine the properties of cells or particles, one cell at a time.
