| dye dilution technique | Method for assessing flow through a system by injection of a known quantity of dye into the system and monitoring its concentration over time at a specific point in the system. (12 Dec 1998) |

| ilizarov technique | A bone fixation technique using an external fixator (fixators, external) for lengthening limbs, correcting pseudarthroses and other deformities, and assisting the healing of otherwise hopeless traumatic or pathological fractures and infections, such as chronic osteomyelitis. The method was devised by the russian orthopedic surgeon gavriil abramovich ilizarov (1921-1992). (12 Dec 1998) |
| immunoperoxidase technique | An immunologic test that utilises antibodies chemically conjugated to the enzyme peroxidase. (05 Mar 2000) |
| indirect technique | indirect method for making inlays |
| Ouchterlony technique | A technique in which both reaction partners (antigen and antibody) are allowed to diffuse to each other in a gel in a precipitation reaction. (05 Mar 2000) |
| technique | The manner of performance, or the details, of any surgical operation, experiment, or mechanical act. See: method, operation, procedure. Synonym: technic. Origin: Fr., fr. G. Technikos, relating to techne, art, skill (05 Mar 2000) |
| 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. (05 Mar 2000) |
| 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) |
