| cold pressor test | A cardiocirculatory challenge conventionally performed by immersing one hand in ice cold water for two or more minutes (as tolerated) to acutely raise the blood pressure, thus imposing resistance to ejection of blood from the left ventricle into the systemic arterial system and consequently acutely increased afterload (afterload = increased left ventricular wall stress). Synonym: Hines-Brown test. (05 Mar 2000) |

| Watson-Schwartz test | A qualitative screening test for diagnosis of acute intermittent porphyria by the addition of Ehrlich's reagent and saturated sodium acetate to the urine; a pink or red colour indicates the presence of porphobilinogen or urobilinogen; the former indicates porphyria, the latter does not; therefore, positive results require further differential extraction with butanol and chloroform to eliminate false-positive results due to urobilinogen.

| college admission test | Test designed to identify students suitable for admission into a graduate or undergraduate curriculum. (12 Dec 1998) |
| Weber's test for hearing | The application of a vibrating tuning fork to one of several points in the midline of the head or face, to ascertain in which ear the sound is heard best by bone conduction, that ear being the affected one if the sound-conducting apparatus (middle ear) is at fault (positive test), but probably the normal one if the neurosensory apparatus is diseased (negative test).

| Webster's test | A test for trinitrotoluene in the urine. (05 Mar 2000) |
| Pirquet's test | A cutaneous tuberculin test. (05 Mar 2000) |
| Weil-Felix test | <investigation> A serologic fluorescent antibody screen that indicates infection with the rickettsial bacteria which is responsible for Rocky Mountain spotted fever. This test may also be positive in brucellosis, salmonella infection and tularaemia. (27 Sep 1997) |
| 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) |
