| analytical chemistry | <study> The branch of chemistry that deals with the quantitative and qualitative identification of substances. (10 Jan 1998) |
| analytical psychology | The theory of psychopathology and the practice of psychotherapy, according to the principles of Jung, which utilises a system of psychology and psychotherapy emphasizing man's symbolic nature, and differs from freudian psychoanalysis especially in placing less significance upon instinctual (sexual) urges. Synonym: analytical psychology. (05 Mar 2000) |
| analytical sensitivity | The degree of response to a change in concentration of analyte being measured in an assay; synonymous with the detection limit. (05 Mar 2000) |
| chemistry, analytical | The branch of chemistry dealing with detection (qualitative) and determination (quantitative) of substances. (12 Dec 1998) |
| antibody specificity | The property of antibodies which enables them to react with some antigenic determinants and not with others. Specificity is dependent on chemical composition, physical forces, and molecular structure at the binding site. (12 Dec 1998) |
| biological specificity | <biology, zoology> The specific, orderly patterns of development and metabolism which define and characterise an individual and its species. (21 Mar 1998) |
| relative specificity | The specificity of a medical screening test as determined by comparison with the same type of test (e.g., specificity of a new serological test relative to specificity of an established serological test). (05 Mar 2000) |
| sensitivity and specificity | Measures for assessing the results of diagnostic and screening tests. Sensitivity represents the proportion of truly diseased persons in a screened population who are identified as being diseased by the test. It is a measure of the probability of correctly diagnosing a condition. Specificity is the proportion of truly nondiseased persons who are so identified by the screening test. It is a measure of the probability of correctly identifying a nondiseased person. (12 Dec 1998) |
| species specificity | Restriction of a characteristic or response to the members of one species; it usually refers to that property of the immune response which differentiates one species from another on the basis of antigen recognition, but the concept is not limited to immunology and is used loosely at levels higher than the species. (12 Dec 1998) |
| specificity | The ability of the immune response to interact with individual antigens. (09 Oct 1997) |
| specificity constant | Ratio of the maximum velocity (Vmax) or kcat to the true Km value for a specific substrate in an enzyme-catalyzed reaction. (05 Mar 2000) |
| substrate specificity | A characteristic feature of enzyme activity in relation to the kind of substrate on which the enzyme or catalytic molecule reacts. (12 Dec 1998) |
| diagnostic specificity | The probability (P) that, given the absence of disease (D), a normal test result (T) excludes disease; i.e., P(T/D). (05 Mar 2000) |
| organ specificity | Restriction of a characteristic or response to a particular organ of the body; it usually refers to that property of the immune response which differentiates one organ from another on the basis of antigen recognition, but the concept is not limited to immunology.
