Sometimes it is possible for a definitive diagnosis to be made from a blood smear. Note: As alternates to this 45-60 minutes in 2.5% Giemsa stain, the smears could be stained for shorter times in more concentrated stains. A blood smear is a blood test used to look for abnormalities in blood cells. Staining procedure for thin blood film 1. smooth even appearance, long straight narrow borders, erythrocytes are distributed in a single layer, red cell area, feathered edge. Allow the methanol-fixed thin smear to dry completely in air (approximately 2 min) by placing the slides on a flat surface. Remove and let air dry. Diff-quick, Cams quick. Blood films are examined in the investigation of hematological (blood) disorders and are routinely employed to look for blood parasites, such as those of malaria and filariasis Ignou student. Kenya Medical Research Institute (KEMRI) [22] [23]. A blood smear scan serves to at least (a) verify the flagged automated hematology results and (b) determine if a man-ual differential leukocyte count needs to be performed. 2. There are numerous valid reasons for a clinician to request a blood smear (Table 1), and these differ somewhat from the reasons why laboratory workers initiate a blood-smear examination. perform the manual differential white blood count, estimate platelet numbers, evaluate the morphology of red blood cells, white blood cells and platelets . If one test is negative and no parasites are found, you will have repeated blood smea One of the most common types of peripheral blood slides is the wedge slide. Images of thin blood smear were obtained from two sources, namely Center f or Disease Control (CDC) [22] and . This paper is arranged as follows. Thus, thick smears allow a more efficient detection of parasites (increased sensitivity). Results of thick and thin blood smears may show: Normal. 3. Results . This test can be used to diagnose, monitor numerous conditions and blood diseases that affect the population of blood cells. The faster the spreader slide is moved, the longer and thinner the smear will be. 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. Dry the slides upright in a rack. Thin blood smears helps doctors discover what species of malaria is causing the infection. The method for staining, concentration and timing of stain used varies according to the purpose, for example, thin blood smears use 1:20 dilution of stock whereas for thick blood smear 1:50 dilution is used. Thin blood is the opposite of thick blood, which can increase the risk of blood clots and complications, such as stroke. https://amzn.to/2Vn4f9N (affiliate link)How to Make & Stain, Thick & Thin Blood Smear. The main purpose of this research is to automatically detect Plasmodium Ovale and Plasmodium Malariae on microscopic thin blood smear digital images. The blood elements (including parasites, if any) are more concentrated (app. A thin blood smear is a drop of blood that is spread across a large area of the slide. diagnosis of malaria should be supported by the identification of the parasites on a _____ 12-24. smears should be obtained _____ hours apart. Experimental result is given in Section III while section IV explains the discussion. Aim of blood smear • Blood films are usually examined to investigate hematological problems (disorders of the blood) and, occasionally, to look for parasites within the blood such as malaria and filaria. This method produces a gradual decrease in thickness of the blood from thick to thin ends with the smear terminating in a feathered edge approximately 2 mm long. The method uses Artificial Neural Net- work (ANN) to test for the presence of plasmodium parasites in thin blood smear images. Leishman stain, also known as Leishman's stain, is used in microscopy for staining blood smears.It is generally used to differentiate between and identify white blood cells, malaria parasites, and trypanosomas.It is based on a methanolic mixture of "polychromed" methylene blue (i.e. thin or thick blood smear. Description of the proposed method and database is described in Section II. Thick smears should be left in buffer for 5 minutes. ADVERTISEMENTS: The smear is greater than 25 mm long and the feathered edge stops approximately 10 mm from the end of the slide.
