A blood smear is a blood test that gives information about the number and shape of blood cells. It is often done as part of or along with a complete blood count CBC. The blood sample is sent to a lab. There, the lab technician looks at it under a microscope. Or, the blood may be examined by an automated machine. When the needle is inserted to draw blood, some people feel moderate pain. Others feel only a prick or stinging.

A blood smear is a blood test that gives information about the number and shape of blood cells. It is often done as part of or along with a complete blood count CBC. Sickle cell anemia is an inherited blood disease in which the red blood cells produce abnormal pigment hemoglobin. The abnormal hemoglobin causes deformity of the red blood cells into crescent or sickle-shapes, as seen in this photomicrograph. This photomicrograph shows one of the abnormal shapes that red blood cells RBCs may assume, a tear-drop shape. Normally, RBCs are round. This photomicrograph shows normal red blood cells RBCs as seen in the microscope after staining.

Analyzed the data: JC CT. Panthothenate kinase-associated neurodegeneration PKAN belongs to a group of hereditary neurodegenerative disorders known as neuroacanthocytosis NA. This genetically heterogeneous group of diseases is characterized by degeneration of neurons in the basal ganglia and by the presence of deformed red blood cells with thorny protrusions, acanthocytes, in the circulation.

All three cell types form in the bone marrow, which is the soft tissue inside your bones. White blood cells help your body fight infections. Platelets help your blood to clot. Blood cell disorders impair the formation and function of one or more of these types of blood cells. Symptoms will vary depending on the type of blood cell disorder. Common symptoms of red blood cell disorders are:.

Many of you have been asking questions about our red blood cell research. You may have seen an image of a red blood cell RBC in the past: it is a small, pink disc, lighter in color in the center than around the sides. It looks lighter in the center because the cell is thinner there, allowing more light to pass through. However, red blood cells can come in many shapes and sizes besides the familiar disc. While some variation is natural and healthy, certain shapes can indicate disease.

Hereditary spherocytosis HS is an inherited blood disease that results in anemia., Poikilocytosis is variation in cell shape: poikilocytes may be oval, teardrop-shaped, sickle-shaped or irregularly contracted.

Everything You Should Know About Poikilocytosis

The structure of red blood cells is affected by many inborn and acquired factors, but in most cases this does not seem to affect their function or survival in physiological conditions. Often, functional deficits become apparent only when they are subjected to biochemical or mechanical stress in vitro , or to pathological conditions in vivo. Our data on the misshapen red blood cells of patients with neuroacanthocytosis illustrate this general mechanism: an abnormal morphology is associated with an increase in the susceptibility of red blood cells to osmotic and mechanical stress, and alters their rheological properties. The underlying mutations may not only affect red cell function, but also render neurons in specific brain areas more susceptible to a concomitant reduction in oxygen supply. Through this mechanism, an increased susceptibility of already compromised red blood cells to physiological stress conditions may constitute an additional risk factor in vulnerable individuals.

Poikilocytosis is the medical term for having abnormally shaped red blood cells RBCs in your blood. Abnormally shaped blood cells are called poikilocytes. Poikilocytes may:. If your RBCs are irregularly shaped, they may not be able to carry enough oxygen. Poikilocytosis is usually caused by another medical condition, such as anemia , liver disease, alcoholism , or an inherited blood disorder. For this reason, the presence of poikilocytes and the shape of the abnormal cells are helpful in diagnosing other medical conditions.

Red blood cells are the most abundant type of blood cells in the human body, delivering oxygen to body tissues. Such abnormalities are detected by viewing the blood-smear images through a microscope, a time consuming and error-prone method. This process can be automated by analyzing the individual cells in a peripheral blood smear image and segmenting the cells using appropriate segmentation techniques. The proposed study aims at Morphologybased detection of abnormal red blood cells in peripheral blood smear images, based on their size and shapes. Variations in the shape of RBCs couldindicate various abnormalities. In the abnormality called Rouleaux the RBCs appear as stack of coins, which are detected by applying a watershed algorithm to individual stacks and counting the number of cells in the stack.
