LEUKEMIA UNDER THE MICROSCOPE When receiving the patient’s sample, the clinical laboratory scientists (medical technologist, cytotechnologist, and cytogenetic technologist) from the medical laboratory department will do an analysis and perform several tests on the patient’s blood samples as well as take a biopsy from the bone marrow. Finally, the pathologist will review, interpret, and make accurate diagnoses from the laboratory results. Finally, a Medical technologist will check for white blood cell counts on the patient for varied laboratory values. Measurements of the white blood cell counts those are increasing above or higher than normal values 4,300100, 600/mm3 (Hart and Loeffler, 2012, Table 10-2, p. 130) will be screened. Medical technologist performs test while the pathologist interprets the laboratory results of a patient diagnosed with leukemia. Leukemic cells in the bone marrow (top right) and peripheral blood (left below) seen under the modern microscope. In conclusion, Leukemia is the leading cause of death by disease in children up to age 14. The good news—mortality rates for childhood cancer have decreased by 66% since 1969. Let’s help providers by giving them the right tools to continuing to fight this deadly disease.
objectives, arm, stage clips, stage, diaphragm, course adjustment knob, light source, fine adjustment knob, and the base. Each of microscope parts has their own function: • The ocular lens (eyepiece) has a magnifying glass that is connected to the body tube, so the individual will able to view the object. • The body tube supports the eyepiece to the nose-piece. • The nose-piece holds at least five objective lenses. Each objective lens can view the image differently when rotating the nose-piece from lower to higher power. Common Objective lenses are 4X, 10X, 100X, and 1000X. • The arm supports all the parts of the microscope. • The stage clips holds the slides for a perfect image when viewing the specimens. It can be move from left to right side. • The fine and course adjustment knob is used for large and small adjustments to view objects. • Light source uses a light to view the slide from underneath. The light is below the diaphragm.
