| enzyme-multiplied immunoassay technique | A type of immunoassay in which the ligand is labelled with an enzyme, and the enzyme-ligand-antibody complex is enzymatically inactive, allowing quantitation of unlabelled ligand. The test uses antibodies that react only with the particular drug for which the sample is being tested. The antibodies attach themselves to the drug if it is present in the sample. It is not designed to measure amounts of the drug present, only to detect its presence or absence. It is used predominantly, but not exclusively, for the detection of drugs of abuse in the urine. See: competitive binding assay, enzyme-linked immunosorbent assay. (05 Mar 2000) |
| Jerne technique | A technique for measuring immunocompetence by quantitating the number of splenic antibody-forming cells found in a mouse that has been sensitised to sheep erythrocytes. The number of plaques formed correlates with the number of splenic antibody-forming cells. (05 Mar 2000) |
| Judkins technique | A method of selective coronary artery catheterization utilizing the standard Seldinger technique through a percutaneous femoral artery puncture. (05 Mar 2000) |
| kleinschmidt monolayer technique | <technique> A method for preparing DNA for study under an electron microscope, the DNA molecules are spread as a thin, positively charged protein film onwater. The film is then transferred to a copper viewing grid andplaced under the microscope. (17 Dec 1997) |
| Ficoll-Hypaque technique | A density-gradient centrifugation technique for separating lymphocytes from other formed elements in the blood; the sample is layered onto a Ficoll-sodium metrizoate gradient of specific density; following centrifugation, lymphocytes are collected from the plasma-Ficoll interface.

| flicker fusion frequency technique | A technique of perimetry using the criterion of critical fusion frequency. Synonym: flicker fusion frequency technique. (05 Mar 2000) |
| fluorescent antibody technique | Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (fluorescent antibody technique, direct) or an indirect method, by formation of antigen-antibody complex which is then labelled with fluorescein-conjugated anti-immunoglobulin antibody (fluorescent antibody technique, indirect). The tissue is then examined by fluorescence microscopy. (12 Dec 1998) |
| fluorescent antibody technique, direct | A form of fluorescent antibody technique utilizing a fluorochrome conjugated to an antibody, which is added directly to a tissue or cell suspension for the detection of a specific antigen. (12 Dec 1998) |
| fluorescent antibody technique, indirect | A form of fluorescent antibody technique commonly used to detect serum antibodies and immune complexes in tissues and microorganisms in specimens from patients with infectious diseases. The technique involves formation of an antigen-antibody complex which is labelled with fluorescein-conjugated anti-immunoglobulin antibody. (12 Dec 1998) |
| flush technique | <procedure> A technique for determining the systolic blood pressure in infants; the elevated limb is milked of blood from the hand or foot proximally; the blood pressure cuff is then inflated above the likely systolic pressure and the limb lowered; the cuff pressure is then gradually released until the blanched limb flushes. (05 Mar 2000) |
| long cone technique | The use of a cone distance of 14 inches or more in making oral roentgenographs. (05 Mar 2000) |
| Abbott's tube | A tube with two lumens, one ending in a small collapsible balloon and the other in a metallic tip with numerous perforations; used for intestinal decompression. Synonym: Abbott's tube. (05 Mar 2000) |
| abdominal ostium of uterine tube | The fimbriated or ovarian extremity of an oviduct. Synonym: ostium abdominale tubae uterinae. (05 Mar 2000) |
| air cells of auditory tube | Occasional small air cells in the inferior wall of the auditory tube, near the tympanic orifice, communicating with the tympanic cavity. Synonym: cellulae pneumaticae tubae auditivae, air cells of auditory tube. (05 Mar 2000) |
