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.

Pappenheimer bodies (Peripheral Blood / May-Grünwald Giemsa and Prussian blue stain) Pappenheimer bodies are abnormal basophilic granules of iron found inside red blood cells on routine blood stain. [1] They are a type of inclusion body composed of ferritin aggregates, or mitochondria or phagosomes containing aggregated ferritin. They appear ...
The staining technique is named after the Russian physician Dmitri Leonidovich Romanowsky (1861–1921), who was one of the first to recognize its potential for use as a blood stain. [6] Stains that are related to or derived from the Romanowsky-type stains include Giemsa, Jenner, Wright, Field, May–Grünwald, Pappenheim and Leishman stains ...
Giemsa stain is used to distinguish all three types of blood smears. [1] The young cells will generally stain gray or blue in the cytoplasm. These young red blood cells are commonly called reticulocytes. All polychromatophilic cells are reticulocytes, however, not all reticulocytes are polychromatophilic.
Stain w/ Giemsa, methylene blue or Wright’s stain. Microscopic examination using an oil immersion lens. (Look for multinucleated giant cells) [7] A modified test can be performed using proprietary agents which requires fewer steps and allows the sample to be fixed quicker.
Codocytes in human blood (Giemsa stain) Target cell compared to other forms of poikilocytosis.Codocytes, also known as target cells, are red blood cells that have the appearance of a shooting target with a bullseye.
Howell–Jolly bodies inside of two normoblasts (center) in bone marrow. Giemsa stain, 1000x. Howell–Jolly bodies are also seen in amyloidosis, severe hemolytic anemia, megaloblastic anemia, hereditary spherocytosis, and myelodysplastic syndrome (MDS). The bodies can also can be seen in premature infants.
