|---|---|
| diagnostic techniques, otological | Methods and procedures for the diagnosis of diseases of the ear or of hearing disorders or demonstration of hearing acuity or loss. (12 Dec 1998) |
| diagnostic techniques, radioisotope | Any diagnostic evaluation using radioactive (unstable) isotopes. This diagnosis includes many nuclear medicine procedures as well as radioimmunoassay tests. (12 Dec 1998) |

| diagnostic techniques, urological | Methods and procedures for the diagnosis of diseases or dysfunction of the urinary tract or its organs or demonstration of its physiological processes. (12 Dec 1998) |
| immunoenzyme techniques | Immunologic techniques based on the use of: 1) enzyme-antibody conjugates; 2) enzyme-antigen conjugates; 3) antienzyme antibody followed by its homologous enzyme; or 4) enzyme-antienzyme complexes. These are used histologically for visualizing or labeling tissue specimens. (12 Dec 1998) |

| indicator dilution techniques | Methods for assessing flow through a system by injection of a known quantity of an indicator, such as a dye, radionuclide, or chilled liquid, into the system and monitoring its concentration over time at a specific point in the system. (12 Dec 1998) |
| investigative techniques | Investigative techniques used in pre-clinical and clinical research, epidemiology, chemistry, immunology, genetics, etc. They do not include techniques specifically applied to diagnosis; therapeutics; anaesthesia and analgesia, surgery, operative, and dentistry. (12 Dec 1998) |
| jaw fixation techniques | The stable placement of surgically induced fractures of the mandible or maxilla through the use of elastics, wire ligatures, arch bars, or other splints. It is used often in the cosmetic surgery of retrognathism and prognathism. (12 Dec 1998) |
| fluorescent antibody techniques | Lab techniques for locating antigens in a prepared tissue sample by using antibodies with fluorescent labels which will bind to the antigens of interest. (09 Oct 1997) |
| genetic | <biology> Pertaining to reproduction or to birth or origin. (07 May 1998) |
| genetic amplification | A process for producing an increase in pertinent genetic material, particularly for increasing the proportion of plasmid DNA to that of bacterial DNA. Includes the production of extrachromosomal copies of the genes for RNA. (05 Mar 2000) |
| genetic assimilation | <genetics> A situation in which a characteristic that is normally expressed only in certain environmental situations becomes fixed in a population so that it no longer requires environmental factors to be expressed. (07 May 1998) |
