Practical Hematology Lab. - LAB 1 -. Introduction. The complete blood count (CBC) is one of the most commonly ordered blood tests. . The . complete blood count is the calculation of the cellular (formed elements) of blood. . Introduction:. WBCs. / Leukocytes are colourless nucleated cell elements.. Larger and lesser in number.. Important in defence mechanism of body.. WBCs. . vs. RBCs:. Larger in size.. Irregular.. Nucleated.. Prepared by:. . Yasser M. EL-. dahdouh. . Red Blood Cell Indices. They are also called red cell absolute values or erythrocyte indices.. Red blood cell indices are measurements that describe the size and oxygen- carrying protein( hemoglobin) content of red blood cells.. Red blood cell indices . Red blood cell indices :. are measurement that describe the size and oxygen carrying protein (HB) content of red blood cells .. The indices are used to help in the differential diagnosis of anemia .. Blood . is the body’s only fluid tissue. It is composed of liquid plasma and formed elements. Formed elements include: . Erythrocytes, or red blood cells (RBCs). Leukocytes, or white blood cells (WBCs). “River of life”. Transports everything that must be carried from one place to another within the body:. Nutrients. Wastes. Heat. Composition of Blood. Blood cells or formed elements:. Red blood cells – transports oxygen. - LAB 1 -. Introduction. The complete blood count (CBC) is one of the most commonly ordered blood tests. . The . complete blood count is the calculation of the cellular (formed elements) of blood. . These . Adult male: 4.6 – 6 million. Adult female: 4.2 – 5 million. Red blood cells are: . Tiny, flexible biconcave discs. Lacks a nucleus. Can bend when going through tiny capillaries. RBC’s are constantly manufactured. highly specialized tissue . composed of more than 4,000 different kinds of components. . .   . Four . of the most important . :. ones . are . red . cells,. . white cells. , . The white blood cell count denotes the number of white blood cells per unit volume of whole blood. Normal WBC count range from 5000-11000 cell / cubic mm this count varies with age.. WBC count is useful to indicate infection or may be employed to follow the progress of certain disease.. In healthy men, the average number of RBCs per cubic millimeter is 5,200,000 (±300,000); . In women, it is 4,700,000 (±300,000).. Hematocrit or Packed cell volume (PCV). Normal adult female Range: 36 - 46 percent. . Print out the Box Counter on a transparency sheet. . Set the magnification to 80x. . Hold the Box Counter transparency over the computer screen. Tape it in place if need be. . Return to . Toolkit. 2. The extra cells cause the blood to be thicker, and this, in turn, increases the risk of other health issues, such as blood clots.. TYPES . Primary polycythemia. Secondary polycythemia. Primary polycythemia is also called polycythemia vera (PV).. Knowing the dilution employed, the red cells number in undiluted blood can easily be calculated.. Normal red cell count. The average red cell counts and their ranges are: . Males = (4.75 – 6.0) . , (5.0 .
