| displacement analysis | General term for an assay in which a binder competes for labelled versus unlabelled ligand; following separation of free and bound ligand, the ligand (the analyte assayed) is quantitated by relating bound and unbound ratios to known standards. See: enzyme-linked immunosorbent assay, radioreceptor assay, immunoassay, enzyme-multiplied immunoassay technique, radioimmunoassay. Synonym: displacement analysis, saturation analysis.

| distributive analysis | The analysis of information gained about the patient and its distribution by the physician, as indicated by the patient's complaint and symptoms. (05 Mar 2000) |
| DNA mutational analysis | Biochemical identification of mutational changes in a nucleotide sequence. (12 Dec 1998) |
| DNA sequence analysis | <molecular biology> Determination of the nucleotide sequence of a length of DNA. Typically, this is performed by cloning the DNA of interest, so that enough can be prepared to allow the sequence to be determined, usually by the Sanger dideoxy chain temination or Maxam Gilbert chain degradation techniques. The resulting reactions are then run on a large sequencing gel, capable of resolving single nucleotide differences in chain length. Recently, PCR based methods have obviated the need to clone the DNA under some conditions and automated DNA sequencing has become widely available. (18 Nov 1997) |
| qualitative analysis | Determination of the nature, as opposed to the quantity, of each of the elements composing a substance. (05 Mar 2000) |
| quantitative analysis | Determination of the amount, as well as the nature, of each of the elements composing a substance. (05 Mar 2000) |
| interaction process analysis | In psychology, analysis of small group behaviour in terms of 12 specific categories, e.g., solidarity, tension release, agreement. (05 Mar 2000) |
| interim analysis | An intermediary analysis of clinical trial data, performed at a point at which enough data have been gathered to derive preliminary, but not necessarily complete conclusions. Interim analyses are performed to see whether continuation of a clinical trial is warranted. (09 Oct 1997) |
| occlusal analysis | A study of the relations of the occlusal surfaces of opposing teeth and their effect upon related structures. Synonym: bite analysis. (05 Mar 2000) |

| training analysis | Psychoanalytic treatment for the purpose of training of an analytic candidate carried out under the official auspices of a psychoanalytic training institute. Synonym: didactic analysis. (05 Mar 2000) |
| transactional analysis | A psychoanalytic therapy wherein each social transaction is analyzed to determine the involved ego state (whether parent-like, child-like, or adult-like) as a basis for understanding behaviour. (12 Dec 1998) |
| equipment failure analysis | Determination of reliability and maintainability of equipment. (12 Dec 1998) |
| factor analysis, statistical | A set of statistical methods for analyzing the correlations among several variables in order to estimate the number of fundamental dimensions that underlie the observed data and to describe and measure those dimensions. It is used frequently in the development of scoring systems for rating scales and questionnaires. (12 Dec 1998) |
