| incontinence of urine | Inability to hold urine in the bladder. This is due to failure of voluntary control over the urinary sphincters resulting in involuntary passage of urine (wetting). (12 Dec 1998) |

| oasthouse urine disease | An inherited metabolic defect in the absorption of methionine which is converted by intestinal bacteria to alpha-hydroxybutyric acid; characterised by diarrhoea, tachypnea, and marked urinary excretion of alpha-hydroxybutyric acid (causing an odour like that of an oasthouse). Origin: oast, kiln for drying hops, malt, or tobacco (05 Mar 2000) |
| febrile urine | Dark coloured, concentrated urine of strong odour, passed by one suffering from fever. Synonym: feverish urine. (05 Mar 2000) |

| urine | <physiology> In mammals, a fluid excretion from the kidneys; in birds and reptiles, a solid or semisolid excretion. In man, the urine is a clear, transparent fluid of an amber colour and peculiar odour, with an average density of 1.02. The average amount excreted in 24 hours is from 40 to 60 ounces (about 1,200 cubic centimeters). Chemically, the urine is mainly an aqueous solution of urea, salt (sodium chloride), and uric acid, together with some hippuric acid and peculiar pigments. It usually has an acid reaction, owing to the presence of acid phosphates of soda or free uric acid. Normally, it contains about 960 parts of water to 40 parts of solid matter, and the daily average excretion is 35 grams (540 grains) of urea.75 gram (11 grains) of uric acid, and 16.5 grams (260 grains) of salt. Abnormally, it may contain sugar as in diabetes, albumen as in Bright's disease, bile pigments as in jaundice, or abnormal quantities of some one or more of the normal constituents. Origin: F. Urine, L. Urina; akin to urinari to plunge under water, to dive, Gr. Urine; cf. Skr. Var water, Icel. R drizzling rain, AS. Waer the sea. Source: Websters Dictionary (01 Mar 1998) |
| urine catecholamine | A test that measures the level of catecholamines or their metabolites in the urine. A 24 hour urine sample is necessary for this assay. Elevations may be seen in pheochromocytoma or neuroblastoma. Normal urine levels of adrenaline should be: 0.5 to 20 mcg/ml and normal urine levels of noradrenaline should be 15 to 80 mcg/ml. (27 Sep 1997) |
| urine immunofixation | A special laboratory technique that is used to identify specific proteins in the blood or urine. It has greatest application in the identification (and monitoring) of monoclonal proteins that are produced in conditions like Waldenstom's macroglobulinaemia and multiple myeloma. (27 Sep 1997) |
| urine metanephrine | A test that measures the level of catecholamines or their metabolites in the urine. A 24 hour urine sample is necessary for this assay. Elevations may be seen in pheochromocytoma or neuroblastoma. Normal urine levels of adrenaline should be: 0.5 to 20 mcg/ml and normal urine levels of noradrenaline should be 15 to 80 mcg/ml.

| amino acid reagent | A reagent used in the identification and quantification of amino acids. (05 Mar 2000) |
| Benedict-Hopkins-Cole reagent | <chemistry> Magnesium glyoxalate, made from a mixture of oxalic acid and magnesium, used for testing proteins for the presence of tryptophan. (12 Aug 2000) |
| biuret reagent | An alkaline solution of copper sulfate. (05 Mar 2000) |
| Mandelin's reagent | A solution of ammonium vanadate in sulfuric acid, used in colour tests for alkaloids. (05 Mar 2000) |
| reagent | <technique> A histochemical technique based on periodic acid oxidation of a substance containing the 1,2-glycol grouping. It is used for staining carbohydrates as the resulting dialdehyde reacts with Schiff reagent to form a coloured product. The adjacent hydroxyl groups are oxidized to form aldehydes by periodic acid (HIO4) and these aldehyde groups react with Schiff's reagent (basic fuchsin decolourised by sulphurous acid) to give a purple colour. Acronym: PAS (18 Nov 1997) |
| reagent kits, diagnostic | Commercially prepared reagent sets, with accessory devices, containing all of the major components and literature necessary to perform one or more designated diagnostic tests or procedures. They may be for laboratory or personal use. (12 Dec 1998) |
| reagent strips | Narrow pieces of material impregnated or covered with a substance used to produce a chemical reaction. The strips are used in detecting, measuring, producing, etc., other substances. (12 Dec 1998) |
