| 3-phosphohistidine 6-phospholysine phosphatase | <enzyme> Mw 150 kD; hydrolyzes not only 6-phospholysine but also 3-phosphohistidine and compounds containing an oxygen-phosphorus (o-p) bond; do not confuse with 6-phospholysine phosphatase (mw 30 kD) which hydrolyzes only 6-phospholysine Registry number: EC 3.1.3.- Synonym: phlpase, p-his p-lys phosphatase, 6-phospholysine 3-phosphohistidine phosphatase (26 Jun 1999) |
| fructose-2,6-bisphosphate 2-phosphatase | <enzyme> Copurifies with 6-phosphofructo-2-kinase; probably is a single protein with both activities; do not confuse with EC 3.1.3.54, fructose-2,6-bisphosphate 6-phosphatase Registry number: EC 3.1.3.46 Synonym: fructose-2,6-diphosphatase, fructose 2,6-bisphosphatase, fructose-2,6-bisphosphatase (26 Jun 1999) |
| fructose-2,6-bisphosphate 6-phosphatase | <enzyme> Do not confuse with fructose-2,6-bisphosphate 2-phosphatase (EC 3.1.3.46) Registry number: EC 3.1.3.54 Synonym: fdp 6-phosphatase, fru(2,6)p2 6-phosphatase (26 Jun 1999) |
| lipid A 4'-phosphatase | <enzyme> Involved in lipid a biosynthesis in rhizobium leguminosarum Registry number: EC 3.1.3.- Synonym: 2-keto-3-deoxyoctulosonate-activated 4'-phosphatase, kdo-activated lipid a 4'-phosphatase (26 Jun 1999) |
| lysophosphatidic acid phosphatase | <enzyme> Forms 1-acyl-sn-glycerol plus pi Registry number: EC 3.1.3.- (26 Jun 1999) |
| 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.

| 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 reflux test | A test to detect gastroesophageal reflux by monitoring oesophageal pH by an electrode in the distal oesophagus either basally or after acid is instilled into the stomach. (05 Mar 2000) |
| ACTH stimulation test | A test for adrenal cortical function; ACTH administered by continuous intravenous infusion, or intramuscularly, evokes an increase in plasma cortisol in normal persons; in adrenal cortical insufficiency, the expected increase in plasma cortisol is limited or nonexistent.
