| capillary resistance test | A tourniquet test used to determine presence of vitamin C deficiency or thrombocytopenia; a circle 2.5 cm in diameter, the upper edge of which is 4 cm below the crease of the elbow, is drawn on the inner aspect of the forearm, pressure midway between the systolic and diastolic blood pressure is applied above the elbow for 15 minutes, and a count of petechiae within the circle is made: 10, normal; 10 to 20, marginal zone; over 20, abnormal. See: Rumpel-Leede test. Synonym: capillary resistance test, vitamin C test. (05 Mar 2000) |

| capon-comb-growth test | A test for androgenic activity, based upon the stimulation of comb growth in capons (castrated cockerels) or immature roosters. Synonym: capon-comb-growth test, cock's comb test. (05 Mar 2000) |
| carbohydrate utilization test | A test for the definitive identification of clinically important yeasts and yeastlike organisms. (05 Mar 2000) |
| Gaddum and Schild test | A sensitive method for identification of epinephrine in tissue or other material, based on the fluorescence of epinephrine exposed to ultraviolet light in the presence of alkali and oxygen; sensitivity ranges from 1:50 to 1:100 million. (05 Mar 2000) |
| Machado-Guerreiro test | A complement-fixation test for infection with Trypanosoma cruzi. (05 Mar 2000) |
| Maclagan's test | Precipitation of abnormal proportions of albumin and globulin from the serum of patients with liver disease by addition of thymol. Although popular in the past it has been superseded by quantitative determination of specific proteins and direct measurement of liver enzymes. Synonym: Maclagan's test, Maclagan's thymol turbidity test. (05 Mar 2000) |
| Maclagan's thymol turbidity test | Precipitation of abnormal proportions of albumin and globulin from the serum of patients with liver disease by addition of thymol. Although popular in the past it has been superseded by quantitative determination of specific proteins and direct measurement of liver enzymes. Synonym: Maclagan's test, Maclagan's thymol turbidity test. (05 Mar 2000) |
| Pachon's test | In a case of aneurysm, determination of the collateral circulation by estimation of the blood pressure. (05 Mar 2000) |
| vaginal cornification test | A test for oestrogenic activity, in which the appearance of cornified epithelial cells in a vaginal smear of a test animal is an indication of the action of an oestrogen. (05 Mar 2000) |
| galactose tolerance test | A liver function test, based on the ability of the liver to convert galactose to glycogen, measured by the rate of excretion of galactose following ingestion or intravenous injection of a known amount; normally, less than 3 g appear in the urine within 5 hours after the ingestion of 40 g. (05 Mar 2000) |
| vaginal mucification test | A test for progestational activity; stimulation of mucus production by the vaginal epithelium in rats, guinea pigs, or mice by progestogens. (05 Mar 2000) |
| macrophage migration inhibition test | A test which measures the presence of migration-inhibitory factor. Usually peritoneal macrophages are placed in a capillary tube in the presence or absence of supernatants from activated T-cells. If MIF is present, the migration of monocyte/macrophages is reduced. Synonym: macrophage migration inhibition test, migration inhibition test. (05 Mar 2000) |
| Valentine's test | The bladder is emptied by passing urine into a series of 3-ounce test tubes, and the contents of the first and the last are examined; the first tube contains the washings from the anterior urethra, the second, material from the bladder, and the last, material from the posterior urethra, prostate, and seminal vesicles. Synonym: Valentine's test. (05 Mar 2000) |
| radioactive iodide uptake test | A test of thyroid function in which 131I-iodide is given orally; after 24 hours, the amount present in the thyroid gland is measured and compared with normal values. Synonym: radioactive iodide uptake test, RAI test. (05 Mar 2000) |
| radioallergosorbent test | An allergy test done on a sample of blood. The aim with rast, as with skin tests, is to check for allergic sensitivity to specific substances. Rast stands for radioallergosorbent test. (12 Dec 1998) |
