| Volhard's test | A test for renal function: the patient drinks 1500 ml of water on an empty stomach; if the patient was not dehydrated beforehand and the kidneys are normal, this fluid will be excreted by the end of 4 hr, with specific gravity of the urine being from 1.001 to 1.004.

| Vollmer test | A tuberculin patch test. (05 Mar 2000) |
| resorcinol test | A test for fructosuria; fresh urine treated with resorcinol in acid gives a red precipitate in the presence of fructose; the precipitate should form a red solution in ethanol. Synonym: Selivanoff's test. (05 Mar 2000) |
| Meinicke test | The first successful application (1917-1918) of immune precipitation to diagnosis of syphilis, now obsolete. (05 Mar 2000) |
| glycosylated haemoglobin test | <investigation> A blood test that measures a person's average blood glucose (sugar) level for the 2- to 3-month period before the test. See: haemoglobin A1C. (09 Oct 1997) |
| Gmelin's test | A test for bile in the urine or other body fluid; nitric acid, with a little nitrous acid, is cautiously added to a few milliliters of the material to be tested; if bile (bilirubin) is present, it is oxidised to varying degrees, thereby resulting in disklike zones that are (from the interface outward) yellow, red, violet, blue, and green; development of green and violet layers is essential to the validity of the test. Synonym: Rosenbach-Gmelin test. (05 Mar 2000) |
| pentagastrin test | An alternative to histamine for stimulation of acid secretion in gastric analysis. (05 Mar 2000) |
| Gofman test | A test for various serum lipoproteins that contain cholesterol, as an index of the tendency to the development of atheromatous lesions and arteriosclerosis; the test is based on the differential flotation of molecules of various sizes when the serum is treated in an ultracentrifuge. (05 Mar 2000) |
| 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) |
