Small basophilic inclusions in red cells which represent precipitated RNA. Peripheral Blood Smear Test Procedure. It may be used to help diagnose and/or monitor numerous conditions that affect blood cell populations. Infections and inflammation such as parasitic infections, Lymphoproliferative disorders such as follicular lymphoma and multiple myeloma. Minimum Volume. Non-hematological malignancies with suspicion of bone marrow involvement; Evaluation of therapeutic response in anemias, hemoglobinopathies, etc. A peripheral smear test can be used to diagnose, monitor numerous conditions and blood diseases that affect population of blood cells. Hence it is very important to use a clean glass slide. QUES 1. 2. Post splenectomy, megaloblastic anemia, hemolytic anemia. Orange-red granules are present in the cytoplasm. Take one drop of venous or capillary blood. PERIPHERAL BLOOD SMEAR STAINING & EXAMINATION – A QUIZ. The Thin Peripheral Blood smear is made by placing a well-mixed drop of blood 1 to 2 mm in diameter & 1/4 inch from the edge of the clean microscopic glass slide. A blood film—or peripheral blood smear—is a thin layer of blood smeared on a glass microscope slide and then stained in such a way as to allow the various blood cells to be examined microscopically. Blood can also be taken from an EDTA sample. The underside of the slide is wiped with tissue paper to remove excess stain. Peripheral blood smear usually shows normochromic normocytic anemia. They are the largest cells with blue-grey ground glass cytoplasm. Prepare a film of blood or bone marrow on a microscopic slide and allow to air dry. RBCs with irregularly spaced projections. Cells of the Immune System Peripheral Blood Smear. This drop of blood is then placed on a clean glass slide about 1 cm from one end in the center line of the slide. Examining the monolayer of a well-prepared and properly stained blood smear allows veterinary technicians to assess erythrocyte (RBC), leukocyte (WBC) and platelet morphology. 3. The blood smear test is often ordered in order to diagnose the cause of: It is important to discuss a few important points with your doctor before undergoing the blood smear test in order to avoid diagnostic errors. The five distinct types of WBCs are: Platelets are fragments of cells that are developed from bone marrow cells called megakaryocytes. Can Progesterone Levels Be Too High In Early Pregnancy?

White blood cells have a nucleus which is surrounded by cytoplasm. Blood smear, alternatively known as peripheral blood smear is a laboratory test in which a thin film of blood is blotted on a microscope slide followed by staining the specimen to permit numerous blood cells to be microscopically observable. Then it is double diluted with distilled water and allowed to stand for about 5–10 minutes. Platelets become activated during injuries and begin to clump together to form blood clots. The nucleus is bilobed. Methods: Thirty-five peripheral blood smears were made from blood specimens counted on an automated blood cell machine: twenty-three thrombocytopenic specimens, 1 with high platelet count and 11 with normal counts. 5. B) Staining of Blood Smear Leave it for 1-2 minutes for fixation of the smear. At one time, a blood smear was prepared on nearly everyone who had a CBC.
