Hematopathology or hemopathology (both also spelled haem-, see spelling differences) is the study of diseases and disorders affecting and found in blood cells, their production, and any organs and tissues involved in hematopoiesis, such as bone marrow, the spleen, and the thymus.
Thick smears allow the microscopist to screen a larger volume of blood and are about eleven times more sensitive than the thin film, so picking up low levels of infection is easier on the thick film, but the appearance of the parasite is much more distorted and therefore distinguishing between the different species can be much more difficult.
Hematology: Blood smears on a glass slide, stained and ready to be examined under the microscope. Bacteriology: Agar plate with bacterial colonies. Bacteriology: microscopic image of a mixture of two types of bacteria stained with the Gram stain. Clinical chemistry: an automated blood chemistry analyser.
Section of bone marrow core biopsy as seen under the microscope (stained with H&E). The preferred sites for the procedure. Bone marrow samples can be obtained by aspiration and trephine biopsy.
Depending on whether an agarose or capillary method is used, interferences vary. Immunoglobulins consist of heavy chains (μ, δ, γ, α, and ε) and light chains (κ and λ). A normal gamma zone should appear as a smooth 'blush', or smear, with no asymmetry or sharp peaks. [12]
The task force has introduced a recommendation that women over the age of 30 test for high-risk human papilloma viruses (HPV) every five years rather than relying on pap smears to detect cervical ...
A bone marrow smear from a case of erythroleukemia. The large cell in the top center is an abnormal erythroblast: it is multinucleated, with megaloblastoid nuclear chromatin. This is diagnostic of erythroleukemia. Cytopathology (sometimes referred to as "cytology") is a branch of pathology that studies and diagnoses diseases on the cellular level.
The laboratory tests comprise complete blood count and peripheral blood smear. [3] The hematopathological findings can reflect both the presence of intravascular hemolysis and the underlying immunological process. [1] [16] The complete blood count usually shows normocytic anemia. Reticulocytosis may be subtle in the acute phase.
