Firstly you have to prepare a blood smear (It should not be too thick and thin) Blood drop should not be very large. Patient's travel history is necessary to aid in test interpretation. A thin peripheral blood film is thus prepared. 6.5.1 Giemsa-stained slides should be carefully stored in slide boxes at The smear is covered with stain for approximately ten minutes, then diluted with water and allowed an additional ten minutes for the cells to properly stain. dip the smear (2-3 dips) into pure methanol for fixation of the smear, leave to air dry for 30seconds Flood the slide with 5% Giemsa stain solution for 20-30 minutes. Place the smear in solution B for 1 second. The key difference between Giemsa Stain and Leishman Stain is that Giemsa staining is useful in the staining of DNA regions of different chromosomes to investigate different aberrations such as translocations and rearrangements, while Leishman stain is useful during blood smear staining and analysis to differentiate and identify trypanosomes, leucocytes and malaria parasites. A blood smear is a test for detecting problems in red blood cells, white blood cells, or platelets. Which stain is used for malaria parasite? Stain with Kinyoun's Rinse briefly with distilled water and drain. The collected blood sample is smeared onto a glass slide and stained with Giemsa stain.

This allows us to determine the presence of malaria and the type of malaria. After one minute, wash the stain from the slide with running water. The purpose of making a smear is to fix the bacteria onto the slide and to prevent the sample from being lost during a staining procedure. On staining with Giemsa stain, the malaria parasite appears with a red or pink nucleus and blue cytoplasm. Malaria was diagnosed in 44 patients by Leishman staining technique and in 65 patients by QBC method.

This glass slide is then examined by a healthcare professional to detect the presence of suspected . The procedure follows these steps: collection of peripheral blood, staining of smear with Giemsa stain and examination of red blood cells for malaria parasites under the microscope. Staining procedure 1: Thin Film staining On a clean dry microscopic glass slide, make a thin film of the specimen (blood) and leave to air dry. Prior to examination, the specimen of the blood smear is stained mostly with Giemsa stain in order to give the parasites a distinctive appearance.

Thick smears are 20-40 times more sensitive than thin smears for screening of Plasmodium parasites, with a detection limit of 10-50 trophozoites/μl. In order to minimize the variation in case management practices, there is Standard Operating procedure for case management of complicated and uncomplicated malaria cases. A good smear preparation is the key to a good stain. This smear is stained with Leishman’s or Giemsa. 0049025. It is mainly used for the demonstration of malarial parasites in blood smears.
