| AGGS | anti-gas gangrene serum |
|---|---|
| BTPS | at body temperature and ambient pressure, and saturated with water vapor [gas] |
| CCGC | capillary column gas chromotography |
| FECO2 | fractional concentration of carbon dioxide in expired gas |
| FEO2, | FEO2 fractional concentration of oxygen in expired gas |
| amino acid analysis | Determination and identification of amino acid content of a macromolecule, identification of a specific amino acid in macromolecules, often a mutated protein, identification and quantitation of amino acid content in blood plasma or urine; a key diagnostic aid.

| analysis | <technique> The separation into component parts or elements, the act of determining the component parts of a substance. Origin: Gr. Lysis = dissolution (18 Nov 1997) |
| analysis of variance | A statistical technique that isolates and assesses the contributions of categorical independent variables to variation in the mean of a continuous dependent variable. (12 Dec 1998) |
| base sequence analysis | <molecular biology> A method, sometimes automated, for determining the base sequence. (09 Oct 1997) |
| bite analysis | A study of the relations of the occlusal surfaces of opposing teeth and their effect upon related structures. Synonym: bite analysis. (05 Mar 2000) |
| bradykinetic analysis | The analysis of a movement by means of slow cinematography. (05 Mar 2000) |
| breath analysis test | A test of hepatic and intestinal absorptive function; aminopyrine labelled with radioactive carbon is administered orally; expired 14CO2 is a measure of aminopyrine absorption and its metabolism in the liver; a measurement of the amount of 14CO2 exhaled after an oral dose of 14C-O-xylose; a measurement of exhaled hydrogen gas following an oral dose of lactose as a test of lactose deficiency. (05 Mar 2000) |
| gastric analysis | Measurement of pH and acid output of stomach contents; basal acid output can be determined by collecting the overnight gastric secretion or by a 1-hr collection; maximal acid output is determined following injection of histamine; output is measured by titration with a strong base. (05 Mar 2000) |
| matched-pair analysis | A type of analysis in which subjects in a study group and a comparison group are made comparable with respect to extraneous factors by individually pairing study subjects with the comparison group subjects (e.g., age-matched controls). (12 Dec 1998) |
| regression analysis | Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see linear models) the relationship is constrained to be a straight line and least-squares analysis is used to determine the best fit. In logistic regression (see logistic models) the dependent variable is qualitative rather than continuously variable and likelihood functions are used to find the best relationship. In multiple regression the dependent variable is considered to depend on more than a single independent variable. (12 Dec 1998) |
| path analysis | A mode of analysis involving assumptions about the direction of causal relationships among linked sequences and configurations of variables. (05 Mar 2000) |
| pedigree analysis | The formal study of the pattern of a trait in a pedigree to determine such properties as its mode of inheritance, age of onset, and variability in phenotype. (05 Mar 2000) |
| volumetric analysis | Quantitative analysis by the addition of graduated amounts of a standard test solution to a solution of a known amount of the substance analyzed, until the reaction is just at an end; depends upon the stoichiometric nature of the reaction between the test solution and the unknown. (05 Mar 2000) |
| cephalometric analysis | A study of the skeletal and dental relationships used in orthodontic case analysis. (05 Mar 2000) |
| percept analysis | Psychologic survey of an individual's personality using Rorschach's series of inkblots. (05 Mar 2000) |
