| citric acid urine test | <investigation> A test which measures the amount of citric acid in the urine. This test is used to diagnose renal tubular acidosis and evaluate those with kidney stones. A below normal level of citric acid in the urine can indicate renal tubular acidosis. Urine citric acid levels can be increased in those with have a high carbohydrate diet, are on oestrogen therapy or vitamin D therapy. (27 Sep 1997) |

| 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.

| 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.
