| red test | An obsolete test for renal function; after the patient has drunk a glass or two of water, 1 ml of a 0.6% solution of dye is injected hypodermically; the time between this injection and the appearance of a pink tinge in the urine as it falls into an alkaline solution is noted; the amount excreted in each of the next 2 hours is then estimated colourimetrically. Synonym: Geraghty's test, phthalein test, red test, Rowntree and Geraghty test. (05 Mar 2000) |
| viability test | <investigation> Test to determine the proportion of living individuals, cells or organisms, in a sample. Viability tests are most commonly performed on cultured cells and usually depend on the ability of living cells to exclude a dye, (an exclusion test) or to specifically take it up (inclusion test). (18 Nov 1997) |

| maximal Histalog test | A test for measurement of maximal production of gastric acidity or anacidity; it is similar to the histamine test, but uses Histalog (betazole hydrochloride), an analogue of histamine. Synonym: maximal Histalog test. (05 Mar 2000) |
| Mazzotti test | A test for onchocerciasis using an oral test dose of diethylcarbamazine (50 or 100 mg), resulting in the appearance of an acute rash in 2 to 24 hours from death of microfilariae in the skin. Synonym: Mazzotti reaction. (05 Mar 2000) |

| McPhail test | A test for progesterone and like substances; immature female rabbits are treated with 150 IU of estrone over a period of 6 days; the test material is then given in five daily subcutaneous doses; progestational proliferation of the endometrium is noted and the results estimated according to a scale from 0 to ++++; the amount required to produce an average (++) response is taken as a unit, equivalent to 0.25 mg of progesterone.
