Fluorescent treponemal antibody absorbed test: A blood serum screening test for syphilis designed to demonstrate the presence or absence of specific antibodies directed against the organism (Treponema pallidum) responsible for syphilis. The fluorescent treponemal antibody absorbed (FTA-ABS) test detects the majority but not all cases of the disease. It is thus a way of screening […]
- Fluoridation
Fluoridation: 1. In general, treatment with fluoride. 2. Specifically, the addition of fluoride to a water supply to help prevent dental caries. For more information, see: Water fluoridation.
- Fluoride
Fluoride: A compound of fluorine with another element or radical. Fluoride containing compounds are used topical and systemic in the prevention of tooth decay. Fluoride ions replace hydroxyl ions in hydroxyapatite in teeth, forming fluorapatite, which leads to fewer cavities. Fluoride compounds are therefore added to some toothpastes and dentists may also give a yearly […]
- Fluorobody
Fluorobody: A hybrid molecule that combines the affinity and specificity of an antibody with the visibility of a green fluorescent protein (GFP). The GSP provides the antibody with a built-in detection system. The creation of the fluorobody in the laboratory was first reported in 2003.
- Fluoroscopy
Fluoroscopy: An x-ray procedure that makes it possible to see internal organs in motion. Fluoroscopy uses x-ray to produce real-time video images. After the x-rays pass through the patient, instead of using film, they are captured by a device called an image intensifier and converted into light. The light is then captured by a TV […]
