To overspread with anything unctuous, viscous, or adhesive; to daub; as, to smear anything with oil.
To soil in any way; to contaminate; to pollute; to stain morally; as, to be smeared with infamy.
Hence, a spot made by, or as by, an unctuous or adhesive substance; a blot or blotch; a daub; a stain.
a sample of cells spread across a glass slide to be examined through a microscope
test done usually every 3 -5 years on the cervix of women over the age of 20 to check for abnormalities
a test to see whether there are TB bacteria in your phlegm. To do this test, lab workers smear the phlegm on a glass slide, stain the slide with a special stain, and look for any TB bacteria on the slide. This test usually takes 1 day to get the results.
a thin tissue or blood sample spread on a glass slide and stained for cytologic examination and diagnosis under a microscope
stain by smearing or daubing with a dirty substance
cover (a surface) by smearing (a substance) over it; "smear the wall with paint"; "daub the ceiling with plaster"
a specimen of cells taken from the female cervix
a very thin layer of blood, on a clean glass slide, from a live animal or one which has recently died
A laboratory technique for preparing a specimen so bacteria can be visualized microscopically. Material from the specimen is spread onto a glass slide (and typically dried and stained). Smear, stain, and microscopy methods for mycobacteria are specific to this genus (see AFB). The slide can be scanned by light or fluorescent high-power microscopy. These methods require ongoing quality assurance for prompt and reliable results. The results for sputum AFB smears typically are reported as numbers of AFB per high-powered microscopy field, or else as a graded result, from no AFB to 4+ AFB. The quantity of stained organisms is associated with degree of infectiousness.
a specimen that has been smeared onto a glass slide, stained, washed in an acid solution, and then placed under the microscope for examination; used to detect acid-fast bacilli in a specimen
A thin tissue or blood sample spread on a glass slide for examination under a microscope. If a person is "smear-positive", this means the lab found some TB bacteria on their smear.
Screening test to detect cancer of the cervix. A scraping of cells is taken from the surface of the cervix and examined under the microscope to see if any of them are showing signs of becoming cancerous. This is a test for pre-cancer. A positive smear does not mean you have cancer. It means you have cells that, if not treated, might go on to develop into cancer.
A laboratory technique for visualizing mycobacteria. The specimen is smeared onto a slide and stained, then examined using a microscope. Smear results should be available within 24 hours. In TB a large number of mycobacteria seen on an AFB smear usually indicates infectiousness. However, a positive result is not diagnostic of TB because organisms other than M. tuberculosis may be seen on an AFB smear (e.g., nontuberculous mycobacteria).
