| Krebs-Ringer solution | A modification of Ringer's solution, prepared by mixing NaCl, KCl, CaCl2, MgSO4, and phosphate buffer, pH 7.4. (05 Mar 2000) |
| labarraque's solution | <medicine> An aqueous solution of hypochlorite of sodium, extensively used as a disinfectant. Origin: From Labarraque, a Parisian apothecary. Source: Websters Dictionary (01 Mar 1998) |
| lactated Ringer's solution | A solution containing NaCl, sodium lactate, CaCl2(dihydrate), and KCl in distilled water; used for the same purposes as Ringer's solution. Synonym: Hartmann's solution. (05 Mar 2000) |

| fowler's solution | An quenous solution of arsenite of potassium, of such strength that one hundred parts represent one part of arsenious acid, or white arsenic; named from Fowler, an English physician who first brought it into use. Source: Websters Dictionary (01 Mar 1998) |
| Locke-Ringer solution | A solution containing NaCl, CaCl2, KCl, MgCl2, NaHCO3, d-glucose, and water; used in the laboratory for physiological and pharmacological experiments. (05 Mar 2000) |
| Lugol's iodine solution | An iodine-potassium iodide solution used as an oxidizing agent, for removal of mercurial fixation artifacts, and also in histochemistry and to stain amoebas. (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.

| 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) |
