The Department of Medical Laboratory Techniques at Al-Mustaqbal University College has organized an Educational Workshop for Third Year Students entitled <br /><br />“Packed Cell Volume”<br /><br />It is remarkable to note that the Worksop Lectures have been delivered by the Academic Mr. Ahmed Hamid Kamil and the Teaching Assistant Ms. Rafif Safaa. Both lecturers have attempted to explain the process of counting Red Blood Cells in both practical and theoretical parts. They have clarified as well that the practical part includes two methods that are used in public laboratories. The first method is Microhematocrit, according to which the percentage of red blood cells is determined through the size of cells, by taking a sample, using the Capillary Method and then placing this sample in a centrifuge to separate blood components. <br />As for the second method, it depends on the Complete Blood Count (CBC) Device. The lecturer has demonstrated to his students the mechanism on which the device operates, where the blood sample is added in an automated manner to the device that contains an isotonic liquid in order to maintain the shape of the pellets. After that the sample is exposed to an electric current through the electrodes connected to the device, forcing the cells to Pass through a special channel that blocks the cells in order to attain an electrical cut, which indicates the form of pulse waves that can be read and converted into numbers on special papers linked to the device itself.<br />
