A blood smear, peripheral blood smear or blood film is a thin layer of blood smeared on a glass microscope slide and ... the monolayer is viewed under a microscope ...
Rouleaux formations are also adopted by spermatozoa as a means of cooperation between genetically similar gametocytes so as to improve reproductive success through enhanced motility and, therefore, fertilization capacity—e.g., the guinea pig. Typical mammalian erythrocytes: (a) seen from surface; (b) in profile, forming rouleaux.
Elliptocytes, also known as ovalocytes or cigar cells, are abnormally shaped red blood cells that appear oval or elongated, from slightly egg-shaped to rod or pencil forms. They have normal central pallor with the hemoglobin appearing concentrated at the ends of the elongated cells when viewed through a light microscope.
A blood cell (also called a hematopoietic cell, hemocyte, or hematocyte) is a cell produced through hematopoiesis and found mainly in the blood. Major types of blood cells include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).

Through the work of Karl von Vierordt, Louis-Charles Malassez, Karl Bürker and others blood cell concentration could by the late 19th century be accurately measured using a blood cell counting chamber, the hemocytometer, and an optical microscope. [3] [4] Until the 1950s the hemocytometer was the standard method to count blood cells. [5]
Physicians specialized in hematology are known as hematologists or haematologists. [2] Their routine work mainly includes the care and treatment of patients with hematological diseases, although some may also work at the hematology laboratory viewing blood films and bone marrow slides under the microscope, interpreting various hematological test results and blood clotting test results.
Rouleaux of red blood cells under the microscope is an artifact which occurs when the blood sample at the edge of the coverslip [15] starts to dry out; where a large number of red blood cells clump together; or when the blood starts to clot when contacted with the glass. These artifacts are observed in only small, selected areas on the slide ...
