| caloric tests | Elicitation of a rotatory nystagmus by stimulating the saemicircular canals with water or air which is above or below body temperature. In warm caloric stimulation a rotatory nystagmus is developed toward the side of the stimulated ear; in cold, away from the stimulated side. Absence of nystagmus indicates the labyrinth is not functioning. (12 Dec 1998) |

| carcinogenicity tests | Tests to experimentally measure the tumour-producing/cancer cell-producing potency of an agent by administering the agent (e.g., benzanthracenes) and observing the quantity of tumours or the cell transformation developed over a given period of time. The carcinogenicity value is usually measured as milligrams of agent administered per tumour developed. Though this test differs from the DNA-repair and bacterial microsome mutagenicity tests, researchers often attempt to correlate the finding of carcinogenicity values and mutagenicity values.

| pancreatic function tests | Tests based on the biochemistry and physiology of the exocrine pancreas and involving analysis of blood, duodenal contents, feces, or urine for products of pancreatic secretion. (12 Dec 1998) |
| 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) |
