Giemsa's solution is a mixture of methylene blue, eosin, and Azure B.The stain is usually prepared from commercially available Giemsa powder. A thin film of the specimen on a microscope slide is fixed in pure methanol for 30 seconds, by immersing it or by putting a few drops of methanol on the slide.
The morphological characteristics of the hematopoietic cells are shown as seen in a Wright’s stain, May-Giemsa stain or May-Grünwald-Giemsa stain. Alternative names of certain cells are indicated between parentheses. Certain cells may have more than one characteristic appearance.
Blood film stained with Giemsa showing Plasmodium (center of image), the parasite that causes malaria infections.. In 1891 Romanowsky [8] [9] [10] developed a stain using a mixture of eosin (typically eosin Y) and aged solutions of methylene blue that formed hues unattributable to the staining components alone: distinctive shades of purple in the chromatin of the cell nucleus and within ...
These cells are often shades of grayish-blue. Polychromasia is usually a sign of bone marrow stress as well as immature red blood cells. 3 types are recognized, with types 1 and 2 being referred to as 'young red blood cells' and type 3 as 'old red blood cells'. Giemsa stain is used to distinguish all three types of blood smears. [1]
Modern complete blood count analyzers can provide an automated white blood cell differential, but they have a limited ability to differentiate immature and abnormal cells, so manual examination of the blood smear is frequently indicated. [5] [6] Blood smear examination is the preferred diagnostic method for certain parasitic infections, such as ...

This stain develops varying colors for all cell structures (“Romanowsky-Giemsa effect) and thus was used in staining neutrophil polymorphs and cell nuclei. Common variants include Wright's stain, Jenner's stain, May-Grunwald stain, Leishman stain and Giemsa stain. All are used to examine blood or bone marrow samples.
