| macro-Kjeldahl method | A procedure for analyzing the content of nitrogenous compounds in urine, serum, or other specimens, usually to determine relatively large amounts of nitrogen (e.g., 20 to 100 mg); the specimen is treated with a digestion mixture (copper sulfate and sulfuric acid), heated thoroughly, and made alkaline with a solution of sodium hydroxide; ammonia is then distilled from the mixture, trapped in a boric acid-indicator solution, and titrated with standard hydrochloric or sulfuric acid.

| Gartner's method | A method of measuring venous pressure, based upon Gartner's vein phenomenon; with the patient sitting erect, a vein is selected on the back of the hand which is held dependent, well below the level of the right atrium, and then is raised slowly; when the vein is observed to collapse, the distance between its level and that of the atrium is measured with a millimeter rule; this distance gives the venous pressure in millimeters of blood; thus the vein itself is used as a manometer communicating with the right atrium; highly inaccurate, especially in elderly subjects.

| parallax method | Localization of a foreign body by observing the direction of its motion on a fluoroscopic screen while moving the X-ray tube or the screen. (05 Mar 2000) |
| Marshall's method | A quantitative procedure for estimating free and conjugated sulfanilamide in body fluids. (05 Mar 2000) |
| Carpue's method | Rhinoplasty utilizing a flap from the forehead. Synonym: Carpue's method, Indian method, Indian operation. (05 Mar 2000) |
| Gerota's method | Injection of the lymphatics with a dye that is soluble in chloroform or ether but not in water; alkannin, red sulfide of mercury, and Prussian blue are said to be suitable for this purpose. (05 Mar 2000) |
| reference method | An analytical procedure sufficiently free of random or systematic error to make it useful for validating proposed new analytical procedures for the same analyte. (05 Mar 2000) |
| Maxam Gilbert method | A method of DNA sequencing, based on the controlled degradation of a DNA fragment in a set of independent, nucleotide specific reactions. The resulting fragments have characteristic sizes depending on the sequence of the template, that can be resolved on a sequencing gel. Although no longer the main protocol, Maxam Gilbert sequencing still has advantages, for example for oligonucleotides or covalently modified DNA. See: dideoxy sequencing. (18 Nov 1997) |
| Rehfuss method | Fractional method of gastric activity: a fine tube with fenestrated metal tip is passed into the stomach after a test meal, and small quantities (6 or 8 ml) of the stomach contents are removed at 15-minute intervals and examined. (05 Mar 2000) |
| Pavlov method | The method of studying conditioned reflex activity by the observation of a motor indicator, such as the salivary or electroencephalographic response. (05 Mar 2000) |
| glucose oxidase method | <chemical pathology> A highly specific method for measurement of glucose in serum or plasma by reaction with glucose oxidase, in which gluconic acid and hydrogen peroxide are formed. (05 Mar 2000) |
| Reverdin's method | pinch graft |
| Charters' method | A method of toothbrushing utilizing a restricted circular motion with the bristles inclined coronally at a 45 degree angle. (05 Mar 2000) |
| Chayes' method | A method of replacing lost teeth utilizing a mechanical device for the fixation and stabilization of the dental prosthesis which allows "movement in function" of the abutment teeth. (05 Mar 2000) |
