fluorescent

 [floo͡-res´ent]
pertaining to or characterized by fluorescence.
fluorescent antibody test a test for the distribution of cells expressing a specific protein by binding antibody specific for the protein and detecting complexes by fluorescent labeling of the antibody. Called also FAB test.
fluorescent treponemal antibody absorption test the standard treponemal antigen test for syphilis: Nonspecific antibodies are removed from patient serum, which is then reacted with Treponema pallidum fixed to a glass slide. Specific antibodies adhering to the treponemes are demonstrated with fluorescein-labeled antihuman globulin. Positive tests are seen in about 85 per cent of cases of primary syphilis, 100 per cent in secondary syphilis, and 98 per cent in late syphilis. The test remains positive for life even after syphilis has been successfully treated. Called also FTA-ABS test.

2. Glowing as if with fluorescence; vivid: bright fluorescent colors.
3. Of or relating to a light bulb that produces visible light by fluorescence, especially a glass tube whose inner wall is coated with a material that fluoresces when an electrical current causes a vapor within the tube to discharge photons.

fluorescent bone marker
tetracycline is used experimentally to mark bone for procedures such as measuring rate of growth of bone.
fluorescent crystals
phosphors used in radiographic intensifying screens. A fine grade of crystals improves the definition of the image obtained but significantly slows the speed of the film. Calcium tungstate was commonly used as the phosphor but is gradually being replaced by rare earths.
fluorescent dye
used in fluorescent staining and fluorescence microscopy.
fluorescent screen
used as a fluoroscopic screen.
fluorescent staining
use of a fluorescent dye linked to an antibody forms the basis for fluorescence microscopy.
