| Montenegro test | A delayed hypersensitivity test for cutaneous leishmaniasis; a positive test when granulomatous induration exceeds 5 min after 2-3 days at the intradermal injection site of a suspension of leishmanias in phenol. Synonym: Montenegro test. Origin: Leishmania + suffix -in, component, derivative (05 Mar 2000) |

| colourimetric caries susceptibility test | A colourimetric test for determining dental caries activity or susceptibility based on the rate of acid production by acidogenic oral microorganisms (e.g., lactobacillus) in a glucose medium, using bromcresol green as the indicator, and producing a colour change from green to yellow. Synonym: colourimetric caries susceptibility test. (05 Mar 2000) |
| colourimetric test | <investigation> A test that depends on a colour change to demonstrate the presence (or absence) of a particular compound or chemical. Examples include home urine pregnancy testing, finger stick blood glucose testing and urinalysis (dip urine). (27 Sep 1997) |
| Werner's test | A thyroid function test used to diagnose difficult cases of hyperthyroidism, now largely replaced by the thyrotropin-releasing hormone stimulation test; triiodothyronine is administered for a week to 10 days, and a reduction of its uptake by the thyroid gland to less than half of the initial uptake is a normal response. Synonym: Werner's test. (05 Mar 2000) |
| 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) |
| pivot shift test | A manoeuvre to detect a deficiency of the anterior cruciate ligament of the knee; when the knee is extended, a sudden subluxation of the lateral tibial condyle upon the distal femur is positive. (05 Mar 2000) |
| P-K test | A test for the presence of immediate hypersensitivity in humans; test serum from an atopic individual is injected intradermally into a normal subject; the normal subject is challenged 24-48 hours later with the antigen suspected of causing the immediate hypersensitivity reaction in the atopic individual. Synonym: P-K test. (05 Mar 2000) |
| Morner's test | For cysteine, which gives a brilliant purple colour with sodium nitroprusside; for tyrosine, which gives a green colour on boiling with sulfuric acid containing formaldehyde. (05 Mar 2000) |
| Wheeler-Johnson test | Cystosine or uracil when treated with bromine yields dialuric acid which gives a green colour with excess of barium hydroxide. (05 Mar 2000) |
| Moschcowitz test | Demonstration of lower limb ischemia by occlusion of the arterial circulation for five minutes with a tourniquet or Esmarch bandage. Following release, skin colour normally will return in a few seconds; with arterial obstruction (e.g., arteriosclerotic) colour returns more slowly. (05 Mar 2000) |
| Mosenthal test | An infrequently used test to evaluate renal concentrating ability by measuring the density of urine every two hours during the ingestion of a controlled diet. (05 Mar 2000) |
| motility test | A test based on microscopic observation or on the spread of growth in soft agar, used to determine if a microorganism is motile. (05 Mar 2000) |
| motility test medium | A culture medium with a concentration of agar that produces a less solid consistency than usual and allows motile organisms to grow away from the line of inoculation; used to differentiate species of bacteria. (05 Mar 2000) |
| Motulsky dye reduction test | A test for glucose-6-phosphate dehydrogenase deficiency in the blood, using a mixture of brilliant cresyl blue, glucose-6-phosphate, and NADP. (05 Mar 2000) |
| widal test | <investigation> A test involving agglutination of typhoid bacilli when they are mixed with serum containing typhoid antibodies from an individual having typhoid fever, used to detect the presence of Salmonella typhi and s. Paratyphi. Pronounced: vidal (13 Nov 1997) |
