| Keating-Hart's method | Fulguration in the treatment of external cancer or of the field of operation after the removal of a malignant growth. (05 Mar 2000) |

| Kendall method | A standard method for estimation of total serum cholesterol involving saponification of cholesterol ester by hydroxide, extraction with petroleum ether, and colour development with acetic anhydride-sulfuric acid; the method avoids interference by bilirubin, protein, and haemoglobin. (05 Mar 2000) |
| ultropaque method | A rapid method for examining thick (1 to 3 mm) sections of fresh tissue with the ultramicroscope, making use of an objective built in an illuminator so that the light is reflected down upon the tissue. (05 Mar 2000) |
| Kety-Schmidt method | A method for measuring organ blood flow first applied to the brain in 1944 by C. F. Schmidt and S. S. Kety. A chemically inert indicator gas is equilibrated with the tissue of the organ of interest and the rate of disappearance from the organ is measured. Blood flow is calculated on the assumption that the tissue and venous blood concentrations of the indicator gas are in diffusion equilibrium at all blood flow rates and that the rate of disappearance of the indicator from the tissue is a function of how much is in the tissue at any time, i.e., it is assumed to be an exponential disappearance.

| zinc sulfate flotation centrifugation method | A flotation method in which the faecal specimen is suspended in tap water, strained through wet gauze, centrifuged, resuspended in tap water, washed and recentrifuged several times, and then suspended in 33% solution of zinc sulfate and centrifuged at top speed for 45 to 60 sec; a bacteriologic loop may be used to pick up the surface layer, which contains protozoan cysts and helminth eggs.

| Fick method | In 1870 A. Fisk proposed that cardiac output can be calculated as the quotient of total body oxygen consumption divided by the difference in oxygen content of arterial blood and mixed venous blood. In the direct Fick method all variables are measured. The indirect Fick method employs a variety of means to avoid measuring mixed venous oxygen content. By extension, the Fick method may be used to measure cardiac output or organ blood flow with any indicator substance for which the rate of uptake or consumption, and the arterial and mixed venous concentrations, can be measured, provided the indicator does not enter or leave the system by any route not being measured. Synonym: Fick principle. (05 Mar 2000) |
| u-score method | An older, simpler, but somewhat less efficient method of linkage analysis than that by maximum likelihood estimation. (05 Mar 2000) |
| flash method | Sterilization of milk by raising it rapidly to a temperature of 178캟, holding it there for a short time, and reducing it rapidly to 40캟. (05 Mar 2000) |
| flotation method | Any of several procedures for concentrating helminth eggs for more reliable results when eggs are difficult to find in direct examination; the flotation method's depend on flotation of helminth eggs on the surface of a liquid of sufficiently high specific gravity, approximately 1.180; 1 part faeces mixed in about 10 parts saturated saline will float most protozoan cysts and nonpercolated helminth eggs. See: zinc sulfate flotation centrifugation method. (05 Mar 2000) |

| Lee-White method | A method for determining coagulation time of venous blood in tubes of standard bore at body temperature. (05 Mar 2000) |
