However, Giemsa requires longer staining time (15 minutes) than NMB. Staining slides involves three methods and procedures explained below: Thin blood smears use 1:20 dilution and the procedure includes: The steps continue to be the same as for thin and thick smear but with the dilute stain of 1:40 dilution that was previously for 1:50 for thick and 1:20 for thin and leave the stain for 1-2 hours.
