| patch tests | Skin tests in which the sensitiser is applied to a patch of cotton cloth or gauze held in place for approximately 48-72 hours. It is used for the elicitation of a contact hypersensitivity reaction. (12 Dec 1998) |
|---|---|
| respiratory function tests | Measurement of the various processes involved in the act of respiration: inspiration, expiration, oxygen and carbon dioxide exchange, lung volume and compliance, etc. (12 Dec 1998) |
| personality tests | Standardised objective tests designed to facilitate the evaluation of personality. (12 Dec 1998) |
| microbial sensitivity tests | Any tests that demonstrate the relative efficacy of different chemotherapeutic agents against specific microorganisms (i.e., bacteria, fungi, viruses). (12 Dec 1998) |
| micronucleus tests | Induction and quantitative measurement of chromosomal damage leading to the formation of micronuclei in cells which have been exposed to genotoxic agents or ionizing radiation. (12 Dec 1998) |
| clinical chemistry tests | Laboratory tests demonstrating the presence of physiologically significant substances in the blood, urine, tissue, and body fluids with application to the diagnosis or therapy of disease. (12 Dec 1998) |
| 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) |
| haemagglutination inhibition tests | Serologic tests in which a known quantity of antigen is added to the serum prior to the addition of a red cell suspension. Reaction result is expressed as the smallest amount of antigen which causes complete inhibition of haemagglutination. (12 Dec 1998) |
| haemagglutination tests | Sensitive tests to measure certain antigens, antibodies, or viruses, using their ability to agglutinate certain erythrocytes. (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) |
