peripheral blood smear anemia

The differential diagnosis (and cause of anemia) can then be further refined based on the results of testing. Peripheral blood smear analysis is a common practice to evaluate health status of a person. When fully developed, the anemia is macrocytic, with MCV > 100 fL/cell in the absence of iron deficiency, thalassemia trait, or renal disease. Spherocytes. - Blood smear too thick - Blood smear too thin - ATL peripheral blood smear - Normal blood smear - Rouleaux in myeloma - CAD blood smear - Hypertriglyceride milky plasma - Macro-ovalocytes - Elliptocytes - Schistocytes on peripheral smear - Helmet cells - Waring blender syndrome - Tear drop cells - Spherocytes - Blood smear, iron deficiency - Polychromatophilia - Lymphocyte and monocyte A Peripheral Blood Smear Examination is a procedure, which involves spreading a drop of blood thinly onto a glass slide. An atlas of instructive blood smears is included as a set of slides. peripheral blood smear, pernicious anemia. Microcytic anemia is defined as the presence of small, often hypochromic, red blood cells in a peripheral blood smear and is usually characterized by a low MCV (less than 83 micron 3). Red blood cell count. In microcytic anemia the curve was shifted to left, in macrocytic anemia the shift was towards right side, and dimorphic anemia shows bimodal peak. Pathophysiology. The majority of the nonhemolytic anemias have a chronic and stable course. Note the macro-ovalocytes with tailed forms characteristic of vitamin B 12 or folate deficiency states. B12 and folic acid. History and physical examination are followed by laboratory testing with a complete blood count and peripheral smear. Significant hypochromia and microcytosis is seen, as well as moderate variation in size and shape of the red cells It can be acquired or inherited. What are the uses of peripheral smear examination. Peripheral Blood Smear. Blood smear abnormalities, as reported … Since physicians are routinely taught to review the peripheral blood smear results of all anemic patients, we analyzed the diagnostic value of the laboratory's blood smear reading and the incremental value of a physician's personal reading in anemic inpatients. Peripheral Blood Smear - Free download as Powerpoint Presentation (.ppt / .pptx), PDF File (.pdf), Text File (.txt) or view presentation slides online. Can take blood in the EDTA. When anemia comes on slowly, the symptoms are often vague and may include feeling tired, weakness, shortness of breath, and a poor ability to exercise. The presence of teardrop cells (dacrocytes) (Figure below) in the peripheral blood, named for their tear drop shape, is a prominent feature of myelophthisic (marrow infiltrative) conditions, including myelofibrosis, hematologic malignancies, cancer metastatic to the bone marrow, and granulomatous diseases. History and physical examination are followed by laboratory testing with a complete blood count and peripheral smear. Keywords: Histogram, RBC, Anemia, Peripheral Smear. Though a lot of studies have been done to assess the efficacy and significance of red blood cell parameters in different hematological conditions fewer efforts have been made to standardize the visual examination of peripheral blood smears for diagnosing anemias. Occasionally they are referred to as “helmet cells” due to their shape. For a blood smear, the lab professional looks for blood cell problems that may not be seen on a computer analysis. An expert examination of the blood smear can identify errors, establish a diagnosis, or lead to a useful fortuitous finding. Prepare the peripheral blood smears. An examination of the blood smear may be requested by physicians or initiated by laboratory staff. Peripheral blood smear. (C) Target cell with a concentration of hemoglobin on its centre.
