A blood film or peripheral blood smear is a thin layer of blood smeared on a microscope slide and then stained in such a way to allow the various blood cells to be examined microscopically. Blood films are usually examined to investigate hematological problems (disorders of the blood) and, occasionally, to look for parasites within the blood such as malaria and filaria.

Famous quotes containing the words blood and/or film:
“Behold that great Plotinus swim
Buffeted by such seas;
Bland Rhadamanthus beckons him,
But the Golden Race looks dim,
Salt blood blocks his eyes.”
—William Butler Yeats (1865–1939)
“Is America a land of God where saints abide for ever? Where golden fields spread fair and broad, where flows the crystal river? Certainly not flush with saints, and a good thing, too, for the saints sent buzzing into man’s ken now are but poor- mouthed ecclesiastical film stars and cliché-shouting publicity agents.
Their little knowledge bringing them nearer to their ignorance,
Ignorance bringing them nearer to death,
But nearness to death no nearer to God.”
—Sean O’Casey (1884–1964)
