Morphology of Erythrocytes (RBC): The erythrocytes are the most numerous blood cells i.e. Cells may be larger or smaller than usual. There are also changes that occur in red blood cells that can give us clues as to underlying diseases. They are also called red cells. Target cells, or codocytes, have an excess of cell membrane relative to cell volume. RBC’s are flexible oval biconcave discs without nucleus; They have peripheral hemoglobin and central pallor of less than 1/3rd of total volume of RBC; Measurements. )These cells are often shades of grayish blue. Before we start with the abnormal morphologies, let’s talk about normal morphology of Red Blood Cells. In this article we will discuss about the morphology of Erythrocytes, Leukocytes and Platelet. For example, small Heinz bodies are commonly seen in the blood of cats without causing anemia. RBC fragments) Previous chapter: Morphological abnormalities of red blood cells.

Red blood cells (RBC) in the urine can signal problems with the urinary tract, kidneys, or bladder. Link: CBC Reference Ranges Basophilic Stippling Red Blood Cell Morphology & Blood Parasites Erythrocytes -The function of a red blood cell is to to distribute oxygen carried by hemoglobin -Most red blood cells do not have a nucleus except in birds, reptiles, and fish -Most are round except for birds, Rationale RBC Count: To evaluate the number of circulating red cells in the blood toward diagnosing disease and monitoring therapeutic treatment.RBC Indices: To evaluate cell size, shape, weight, and hemoglobin (Hgb) concentration. Spherocytosis. Macrocytic target cells can be seen in liver disease, and microcytic target cells may be seen in thalassemia. 2-4 An increase in the RDW would indicate a higher presence of anisocytosis on the peripheral blood smear. The bottom image on the right illustrates the two distinct peaks that are observed on the RBC histogram from the automated hematology analyzer. One is the patient's basic red cell population; the other is a second population with distinct morphological features. Name any abnormal RBC morphology present in this field of perhipheral blood. 2-4 Get more help from Chegg. The MCV may be increased (macrocytosis) or decreased (microcytosis). Nursing Central is an award-winning, complete mobile solution for nurses and students. RBC and WBC morphology. This condition is reversible, and more often than not, it is a side effect of the EDTA anticoagulant coating in the vacutainer used to collect to blood to prevent it from clotting. 4. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Figure 4-26. Similar to the RBC indices, it is determined by automated cell counting instruments and is used to predict the degree of red blood cell size variation, known as anisocytosis. Red blood cell morphology usually plays a small but important role in this differentiation of megaloblastic from nonmegaloblastic causes. Estimation of the platelet count II. Firstly, is the abnormal morphology seen in every field to be examined ? Quickly memorize the terms, phrases and much more. Morphology of platelets and platelet count Presence of parasites What is the normal RBC morphology. A ghost RBC (arrow) is noted in the center of the field and suggests some degree of intravascular lysis (100x). -- The first section of this topic is shown below --Synonym/Acronym: RBC. It can be caused by various anemias, such as iron deficiency where the cells will be smaller than normal pernicious anemia, where cells are larger than normal (B12 deficiency). Macrocytosis is a term used to describe red blood cells that are larger than normal. Agglutination can falsely increase the MCV. Barbara J. Bain, in Dacie and Lewis Practical Haematology (Twelfth Edition), 2017. Normal mature RBC are biconcave, round discs that are about 6 – 8 in diameter, which is only slightly smaller than the normal small mature lymphocytes ( about 6 – 10 in diameter). Diameter – 7- 8µm Anisocytosis is a condition in which the red blood cells are not even in size. Red Blood Cell Maturation. 1. Red Blood Cell Distribution Width (RDW) RDW is the coefficient of variation or standard deviation of the MCV. RBC- Morphology. If both macrocytes and microcytes are present, the MCV may be normal. Red Blood Cell Morphology Red blood cells (erythrocytes) are biconcave disks with a diameter of 7-8 microns, which is similar to the size of the nucleus of a resting lymphocyte. STUDY. Head, body and tail. Polychromasia (πολθζ, many)The term ‘ polychromasia ’ suggests that the red cells are being stained many colours. The distinct populations can be observed in the top image on the right. Echinocytes are red blood cells with abnormal cell membranes that cause them to appear "spiked" or like a sea urchin.For this reason, they are also called Burr cells. Evidence of haemolysis may be present (eg. Also known as megalocytosis or macrocythemia, this condition typically causes no signs or symptoms and is usually detected incidentally on routine blood tests. Log in Sign up.

Polychromasia is a disorder where there is an abnormally high number of immature red blood cells found in the bloodstream as a result of being prematurely released from the bone marrow during blood formation. It’s an indication of red blood cells being released prematurely from bone marrow during formation. Otherwise, the analysis of cell morphology may be greatly distorted by poorly made and poorly stained smear. A well-stained smear is also important. Large platelets can be seen when platelet turnover is increased (as in immune thrombocytopenic purpura). Start studying RBC- Morphology. In man and in all mammals, erythrocytes are devoid of a nucleus and have the shape of a biconcave lens. This can be accomplished most efficiently by categorizing the anemia’s morphology.
