| placental function tests | Methods used for the assessment of placental function. (12 Dec 1998) |
|---|---|
| complement fixation tests | Serologic tests based on inactivation of complement by the antigen-antibody complex (stage 1). Binding of free complement can be visualised by addition of a second antigen-antibody system such as red cells and appropriate red cell antibody (haemolysin) requiring complement for its completion (stage 2). Failure of the red cells to lyse indicates that a specific antigen-antibody reaction has taken place in stage 1. If red cells lyse, free complement is present indicating no antigen-antibody reaction occurred in stage 1. (12 Dec 1998) |
| word association tests | Lists of words to which individuals are asked to respond ascertaining the conceptual meaning held by the individual. (12 Dec 1998) |
| mutagenicity tests | Tests of chemical substances and physical agents for mutagenic potential. They include microbial, insect, mammalian cell, and whole animal tests. (12 Dec 1998) |
| haematologic tests | Tests used in the analysis of the hemic system. (12 Dec 1998) |
| precipitin tests | Serologic tests in which a positive reaction manifested by visible precipitation occurs when a soluble antigen reacts with its antibody. (12 Dec 1998) |
| predictive value of tests | In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test. (12 Dec 1998) |
| pregnancy tests | Tests to determine whether or not an individual is pregnant. (12 Dec 1998) |
| cytotoxicity tests, immunologic | The demonstration of the cytotoxic effect on a target cell of a lymphocyte, a mediator released by a sensitised lymphocyte, an antibody, or complement. (12 Dec 1998) |
| psychological tests | Standardised tests designed to measure abilities, as in intelligence, aptitude, and achievement tests, or to evaluate personality traits. (12 Dec 1998) |
| psychomotor tests | Psychological test's which, although based on other psychological processes (e.g., sensory, perceptual), require a motor reaction such as copying designs, building blocks, or manipulating controls. (05 Mar 2000) |
| serologic tests | Diagnostic procedures involving immunoglobulin reactions. (12 Dec 1998) |
| skin tests | Epicutaneous or intradermal application of a sensitiser for demonstration of either delayed or immediate hypersensitivity. Used in diagnosis of hypersensitivity or as a test for cellular immunity. (12 Dec 1998) |
| speech articulation tests | Tests of accuracy in pronouncing speech sounds, e.g., iowa pressure articulation test, deep test of articulation, templin-darley tests of articulation, goldman-fristoe test of articulation, screening speech articulation test, arizona articulation proficiency scale. (12 Dec 1998) |
| speech discrimination tests | Tests of the ability to hear and understand speech as determined by scoring the number of words in a word list repeated correctly. (12 Dec 1998) |
