Why Leishman stain is used in blood smear?
Leishman’s staining method for thin and thick smears is a good alternative to Giemsa’s stain for identifying Plasmodium parasites. The Leishman method is superior for visualization of red and white blood cell morphology.
Does Leishman stain contain methanol?
It is based on a methanolic mixture of “polychromed” methylene blue (i.e. demethylated into various azures) and eosin. The methanolic stock solution is stable and also serves the purpose of directly fixing the smear eliminating a prefixing step.
How is Leishman stain prepared?
2) Cover the film with Leishman’s Stain (S018S) and allow to act for 1 minute. Methanol in the stain fixes the preparation. 3) Add double the volume of distilled water to the slide and mix. 4) Allow the diluted stain to act for 10-12 minutes.

How do I Clean my slides with Leishman’s stain?
Procedure: 1 Use smears that are as thin as possible and air-dried. 2 Fully cover the smears with Leishman’s Stain solution. Stain for 2 minuted. 3 Add twice the amount of distilled water and mix by swirling. Incubate for at least 10 min. 4 Rinse thoroughly with distilled water. 5 Dry the slides using blotting paper and air-dry More
What is Leishman and Giemsa (L&G) stain?
We created a newer modification of the conventional Leishman and Giemsa stains as Leishman and Giemsa (L&G) stain and compared the efficacy and reliability of this stain with conventional stains. The study was performed to evaluate the staining efficacy, feasibility, time and cost of L&G stain over the conventional Leishman and Giemsa stains.
What are the stains used in hematology laboratory?
Therefore, the stains used in Hematology laboratory are the combination of these three types of stains. Besides the dyes, a buffer is added to the stain which acts as the mordant and enhances the staining reaction, results in the better morphology of the blood cells under the microscope.
