Blood film
Blood Film
A Blood Film (pronounced: /blʌd fɪlm/), also known as a Peripheral Blood Smear or Peripheral Smear, is a thin layer of blood smeared on a glass microscope slide and then stained in order to be examined under a microscope.
Etymology
The term "Blood Film" is derived from the process of smearing a thin film of blood on a slide for examination. The word "blood" comes from the Old English blōd, and "film" from the Old English filmen, meaning membrane or thin skin.
Procedure
The Blood Film procedure involves the collection of a blood sample, usually from a peripheral vein. The sample is then smeared on a glass slide, creating a thin film of blood. This film is then stained using a special dye, which allows for the examination of the blood cells under a microscope.
Interpretation
The interpretation of a Blood Film involves the examination of the blood cells under a microscope. This can provide information about the number, size, and shape of the blood cells, as well as any abnormalities that may be present. This can help in the diagnosis of various medical conditions, such as anemia, infections, and blood cancers.
