           There are two methods for counting RBCs; 1) Automated method through the electronic blood cells counter. 2) Manual method using the hemocytometer. Electronic counter is more accurate than the hemocytometer method. The electronic counter is expensive, needs periodical maintenance. Maintenance of blood counter is very important; failure to do that will result in misleading results. […]

           An anticoagulant is a preservative that used to preserve the blood sample in a state similar to its state inside the body. An anticoagulant that is used for cbc must be neither affecting the structure of the formed elements of blood, nor produce any dilution to the plasma. Ethylene Diamine Tetra-acetic acid (EDTA) is considered […]

           Anemia is a blood disorder, it is not a disease, but it is a sign for a disease. Anemia is defined as the decrease in red blood cells count or hemoglobin concentration or both per unit volume of blood. This means that the decrease of either red blood cells count alone or hemoglobin concentration alone […]

           Prof. Mahmoud Rushdi (Assiut University-Egypt) Definition Polycythemia is the increase of RBCs count above the normal upper limit specific for each animal species. There are two types of polycythemia, which are relative and absolute polycythemia. Relative polycythemia is defined as the relative increase of RBCs count due to loss of fluids from the body. The […]

           Three values are calculated mathematically and used mainly to measure the average size of the RBC, average hemoglobin weight and percent of hemoglobin per individual erythrocyte. The mean corpuscular values are: – Mean corpuscular volume (MCV), MCV is obtained by dividing the value of packed cells volume (PCV) on the RBCs count, and then multiply […]

           Hemoglobin (Hb) is the red pigment that contained in the RBCs, its major function is to bind oxygen and transport it to the tissues and to bind CO2 and carry it back from the tissues to the lungs. Hemoglobin has the same life span of the RBCs, after the engulfing of old RBCs by the […]

           Prof. Mahmoud Rushdi (Assiut University-Egypt) Hematological analysis is concerned with the analysis of the cellular component of blood including tests that used for evaluation of erythrocytes, leucocytes and platelets. Blood sample for complete blood count (CBC) must be collected on EDTA as anticoagulant. Evaluation of the erythrocytes picture involve measuring red blood cells (RBCs) count, […]
