| Meltzer-Lyon test | A test used in diagnosis of gallbladder conditions: 25 ml of a 25% solution of magnesium sulfate are delivered into the region of the sphincter of Oddi through a duodenal tube, causing contraction of the gallbladder, relaxation of the sphincter, and the expulsion of bile from the common duct and gallbladder; bile from the common duct is relatively pale and is expelled first, that from the gallbladder follows; samples aspirated from the tube are examined for pus cells, pigment granules, epithelial cells, cholesterol, etc. (05 Mar 2000) |

| Goldscheider's test | Determination of the temperature sense by touching the skin with a sharp-pointed metallic rod, heated to varying degrees. (05 Mar 2000) |
| gold sol test | An obsolete, non-specific test for altered proteins in spinal fluid. As originally used by Lange in 1912, the test was thought to be specific for neurosyphilis; however, this proved to be incorrect. Dilutions of spinal fluid are made in saline and to these a colloidal gold solution is added; if altered proteins are present, there is a colour change or precipitate formed. at present, its chief use is to demonstrate cerebrospinal fluid protein abnormalities in multiple sclerosis. Synonym: gold sol test, Zsigmondy's test. (05 Mar 2000) |
| CF test | <immunology> Binding of complement as a result of its interaction with immune complexes (the classical pathway) or particular surfaces (alternative pathway). (18 Nov 1997) |
| Goodenough draw-alpha-man test | A brief test for assessing an individual's level of intelligence based on how accurately drawn and how many elements are included when a child or adult is given a pencil and sheet of white paper and asked to draw a man, the best man he or she is able to draw. Also called the Goodenough draw-alpha-person test and, in its current form, the Goodenough-Harris drawing test. (05 Mar 2000) |
| goodness of fit test | A statistical test of the hypothesis that data have been randomly sampled or generated from a population that follows a particular theoretical distribution. (05 Mar 2000) |
| Reuss' test | A test for atropine; the addition of oxidizing agents and sulfuric acid to a liquid containing atropine produces an odour of orange-flowers and roses. (05 Mar 2000) |
| performance test | A test, such as five of the eleven Wechsler adult intelligence scale subtests, requiring little or no verbal instruction from the examiner and virtually no verbal response by the examinee. (05 Mar 2000) |
| Gothlin's test | <investigation> A capillary fragility test to determine the presence or absence of scurvy. (05 Mar 2000) |
| Rh blocking test | A test for nonagglutinating Rh antibodies: an Rh agglutination test is first carried out; if the test for Rh agglutinins is negative, then 1 drop of anti-Rho agglutinating serum of moderate titre is mixed with the patient's serum containing Rh-positive test cells; if after incubating for from 1 to 2 hr at 37캜 no agglutination occurs, Rho-blocking antibodies are assumed to be present in the patient's serum.

| Graham-Cole test | Radiography of the gallbladder after ingestion of a contrast medium. (12 Dec 1998) |
| chemotherapy drug sensitivity test | <investigation> A test to assess a cancerous tissue's response and vulnerability to chemotherapy drugs. This test can help predict a patients response to treatment and suggest which drugs may be useful. (16 Dec 1997) |
| Chick-Martin test | A method of testing the in vitro efficiency of a bactericidal agent; a standard culture of Salmonella typhi which has been added to a fixed amount of sterilised faeces or yeast is tested for a fixed period (30 minutes), against various concentrations of phenol solution and various concentrations of the disinfectant; the result is expressed as a ratio: the phenol coefficient, which is the highest dilution of the disinfectant under test at which the bacteria are killed, divided by the highest dilution of phenol which sterilises the solution in the same length of time. (05 Mar 2000) |
| chi-square test | A statistical method of assessing the significance of a difference, as when the data from two or more samples is represented by a discrete number such as the numbers of females and males attending each of two colleges. Synonym: x2 test. (05 Mar 2000) |
| metabisulfite test | A test for sickle cell haemoglobin (Hb S); deoxygenation of cells containing Hb S is enhanced by addition of sodium metabisulfite to the blood, causing sickling visible on a slide; certain other abnormal haemoglobins (Hb CHarlem and Hb I) also sickle in this test.
