| fasting blood glucose | <endocrinology, investigation> A method for finding out how much glucose (sugar) is in the blood. The test can show if a person has diabetes. A blood sample is taken in a lab or doctor's office. The test is usually done in the morning before the person has eaten. The normal, nondiabetic range for blood glucose is from 70 to 110 mg/dl, depending on the type of blood being tested. If the level is over 140 mg/dl, it usually means the person has diabetes (except for newborns and some pregnant women). (09 Oct 1997) |

| fasting glucose | <endocrinology, investigation> A measurement of the blood glucose in the morning prior to the ingestion of any food for the prior 12 hours. (27 Sep 1997) |
| UPD-glucose-thiohydroximate glucosyltransferase | <enzyme> From brassica; catalyses the glucosylation of phenylacetothiohydroximate in the presence of udp-glucose to form desulfobenzylglucosinolate Registry number: EC 2.4.1.- Synonym: udp-glc-th-glucosyltransferase (26 Jun 1999) |
| uridine diphosphate glucose | <chemical> A key intermediate in carbohydrate metabolism. Serves as a precursor of glycogen, can be metabolised into udpgalactose and udpglucuronic acid which can then be incorporated into polysaccharides as galactose and glucuronic acid. Also serves as a precursor of sucrose lipopolysaccharides, and glycosphingolipids. Chemical name: Uridine 5'-(trihydrogen diphosphate), P'-alpha-D-glucopyranosyl ester (12 Dec 1998) |
| uridine diphosphate glucose dehydrogenase | <enzyme> An enzyme that catalyses the oxidation of udpglucose to udpglucuronate in the presence of NAD+. Chemical name: UDPglucose:NAD+ 6-oxidoreductase Registry number: EC 1.1.1.22 (12 Dec 1998) |
| utp-glucose-1-phosphate uridylyltransferase | <enzyme> An enzyme that catalyses the formation of udpglucose from utp plus glucose 1-phosphate. Chemical name: UTP:alpha-D-glucose-1-phosphate uridylyltransferase Registry number: EC 2.7.7.9 (12 Dec 1998) |
| 4-coumaroyl-D-glucose hydroxylase | <enzyme> From sweet potato roots (ipomoea batatas); catalyses the conversion of p-coumaroyl-d-glucose to caffeoyl-d-glucose for chlorogenic acid biosynthesis in the presence of ascorbic acid; mw 33 kD; has weak polyphenol oxidase activity; also hydroxylates p-coumaric acid Registry number: EC 1.14.17.- Synonym: p-coumaroyl-d-glucose hydroxylase, cdg hydroxylase (26 Jun 1999) |
| liquid glucose | A pharmaceutic aid consisting of dextrose, dextrins, maltose, and water, obtained by the incomplete hydrolysis of starch. (05 Mar 2000) |
| Abbe test plate | <equipment> A long, wedge-shaped coverslip about 0.20 mm thick at one end and 0.10 to 0.12 mm at the other end coated chemically with a silver film on which are ruled horizontal lines. at each variation in thickness of 0.01 mm there are vertical lines. By means of oblique illumination and by focusing on different portions of the plate, it is possible to determine the optimum coverslip thickness for any objective and also, for microscopes with drawtubes, the tube length for best objective performance. The approximate freedom from spherical and chromatic aberrations can also be estimated. Small isolated bits of silver near the edges of the lines form good objects for the star test (05 Aug 1998) |
| acetone test | A test for ketonuria; the suspected urine is shaken up with a few drops of sodium nitroprusside, and strong ammonia water is then gently poured over the mixture; if acetone is present, a magenta ring forms at the line of contact; tablets containing sodium nitroprusside and alkali are now more commonly used. (05 Mar 2000) |
| achievement test | A standardised test used to measure acquired learning, e.g., competence in a specific subject area such as reading or arithmetic, in contrast to an intelligence test which is a useful index of potential ability or learning. (05 Mar 2000) |
| acidified serum test | Lysis of the patient's red cells in acidified fresh serum, specific for paroxysmal nocturnal haemoglobinuria. Synonym: Ham's test. (05 Mar 2000) |
| acid loading test | <nephrology> This is a test used in the diagnosis of renal tubular acidosis. The patient takes ammonium chloride capsules for 3 days to acidify the blood (lower blood pH). A sample of the urine and the blood is then collected and the results are interpreted. (27 Sep 1997) |
| acid perfusion test | <gastroenterology, investigation> A test used to diagnosis gastrooesophageal reflux disease. This investigation requires that the patient swallow 3 tiny tubes into the stomach. A mixture of hydrochloric acid (like stomach acid) and saline are alternatively injected into the tubes. The patient then reports any symptoms they may have. Some patients may vomit. (13 Nov 1997) |
| acid phosphatase test for semen | A screening test for semen by determining acid phosphatase content; because seminal fluid contains high concentrations of acid phosphatase, while other body fluids and extraneous foreign materials have very low concentrations, high values of acid phosphatase on vaginal aspirate or lavage, or on wash fluid from stains, render positive identification of semen, even if the male is aspermic.
