| visual field test | <ophthalmology> A test which measures the extent of visual field loss. This test may be performed by a number of methods including confrontation, tangent screen exam and automated perimetry. Diseases that affect visual field include stroke, diabetes, hypertension, multiple sclerosis, glaucoma, hyperthyroidism, Jacob-Creutzfeldt disease and optic glioma. (27 Sep 1997) |

| glove juice test | <investigation> A test of how effective a particular antimicrobial surgical hand scrub is at disinfecting. (09 Oct 1997) |
| vitality test | A group of thermal and electrical test's used to aid in assessment of dental pulp health. Synonym: pulp test. (05 Mar 2000) |
| PBI test | A formerly used test of thyroid function in which serum protein-bound iodine is measured to provide an estimate of hormone bound to protein in peripheral blood. Synonym: PBI test. (05 Mar 2000) |
| PCR test | <investigation> A very sensitive test that measures the presence or amount of RNA or DNA of a specific organism or virus (for example: HIV or CMV) in the blood or tissue. PCR tests such as HoffmannLa Roche's HIV RT PCR are being used to gauge HIV disease progression and the effect of particular treatments on HIV infection. (09 Oct 1997) |
| vitamin B12 absorption test | <investigation> This test measures the amount of vitamin B12 in the urine after ingesting a dose of B12. This test evaluates vitamin B12 absorption. The cells in the stomach produce a substance known as intrinsic factor. This substance combines with B12 to allow absorption in the distal ileum. The patient is given a small dose of radioactive B12 which can then be detected in the patients urine. Pernicious anaemia is the clinical result of B12 deficiency. Conditions that can result in an abnormal Schilling test include: deficiency of intrinsic factor, malabsorption or the development of an antibody to intrinsic factor. The Schilling test can be performed with or without administration of intrinsic factor to determine what the underlying cause for pernicious anaemia. Laxative use, renal insufficiency and hypothyroidism can all interfere with the results of this test. (27 Sep 1997) |
| vitamin C 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) |
| glucose oxidase paper strip test | <chemical pathology> A qualitative test for glucose in the urine, in which glucose is oxidised to gluconic acid by glucose oxidase; a specific test, unless ascorbic acid is present. (05 Mar 2000) |
| glucose tolerance test | <chemical pathology, investigation> A special test where the blood glucose is measure in intervals after a glucose-rich meal is taken, a test used for diagnosing diabetes. (27 Sep 1997) |
| VMA test | A test for catecholamine-secreting tumours (pheochromocytoma and neuroblastoma) performed on a 24-hr urine specimen; it is based on the fact that vanillylmandelic acid is the major urinary metabolite of norepinephrine and epinephrine. Synonym: 3-methoxy-4-hydroxymandelic acid test, VMA test. (05 Mar 2000) |
| 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. (05 Mar 2000) |
| 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) |
