| value | 1. The property or aggregate properties of a thing by which it is rendered useful or desirable, or the degree of such property or sum of properties; worth; excellence; utility; importance. "Ye are all physicians of no value." (Job xiii. 4) "Ye are of more value than many sparrows." (Matt. X. 31) "Caesar is well acquainted with your virtue, And therefore sets this value on your life." (Addison) "Before events shall have decided on the value of the measures." (Marshall) 2. Worth estimated by any standard of purchasing power, especially by the market price, or the amount of money agreed upon as an equivalent to the utility and cost of anything. "An article may be possessed of the highest degree of utility, or power to minister to our wants and enjoyments, and may be universally made use of, without possessing exchangeable value." (M'Culloch) "Value is the power to command commodities generally." (A. L. Chapin (Johnson's Cys)) "Value is the generic term which expresses power in exchange." (F. A. Walker) "His design was not to pay him the value of his pictures, because they were above any price." (Dryden) In political economy, value is often distinguished as intrinsic and exchangeable. Intrinsic value is the same as utility or adaptation to satisfy the desires or wants of men. Exchangeable value is that in an article or product which disposes individuals to give for it some quantity of labour, or some other article or product obtainable by labour; as, pure air has an intrinsic value, but generally not an exchangeable value. 3. Precise signification; import; as, the value of a word; the value of a legal instrument 4. Esteem; regard. "My relation to the person was so near, and my value for him so great" (Bp. Burnet) 5. The relative length or duration of a tone or note, answering to quantity in prosody; thus, a quarter note has the value of two eighth notes . 6. In an artistical composition, the character of any one part in its relation to other parts and to the whole; often used in the plural; as, the values are well given, or well maintained. 7. Valor. Alternative forms: valew] Value received, a phrase usually employed in a bill of exchange or a promissory note, to denote that a consideration has been given for it. Origin: OF. Value, fr. Valoir, p. P. Valu, to be worth, fr. L. Valere to be strong, to be worth. See Valiant. Source: Websters Dictionary (01 Mar 1998) |

| maturation value | An indicator of the level of maturation attained by vaginal epithelium and used as a factor in cytohormonal evaluation from the maturation index by valuing the parabasal cells at 0.0, the intermediate cells at 0.5, and the superficial cells at 1.0; for special investigations, subtypes of a major cell can be given different values's.

| relative value scales | Coded listings of physician or other professional services using units that indicate the relative value of the various services they perform. They take into account time, skill, and overhead cost required for each service, but generally do not consider the relative cost-effectiveness. Appropriate conversion factors can be used to translate the abstract units of the relative value scales into dollar fees for each service based on work expended, practice costs, and training costs.

| ceiling value | <pharmacology> The ceiling value is the maximum safe airborne concentration of a potentially toxic substance and is a concentration that should never be exceeded in an area where people are breathing. (26 Mar 1998) |
| gray level also gray value | <microscopy> The brightness of pixels in a digitised video image, commonly expressed in integers ranging from 0 (black) to 255 (white) for an 8-bit digital signal. (05 Aug 1998) |
| gross heating value | (GHV) The maximum potential energy in the fuel as received. It reflects the displacement of fibre by water present in the fuel. Expressed as: GHV = HHV (1 - MC / 100) (05 Dec 1998) |
| phenotypic value | In quantitative genetics, the metrical quantity of some trait associated with a particular phenotype. (05 Mar 2000) |
| Wilder's law of initial value | The direction of response of a body function to any agent depends to a large degree on the initial level of that function. Synonym: law of initial value. (05 Mar 2000) |
| CT value | <molecular biology> Concentration of DNA molecules (in moles) multiplied by time. The value is used to plot the renaturing (complementary single strands of DNA spontaneously forming into a double-stranded molecule) of DNA after it has been denatured (DNA molecule which has been broken into two individual single strands). (26 Mar 1998) |
| C value | <molecular biology> A measure of the amount of DNA in the haploid genome of an organism, which can be by mass or by molecular weight. (13 Nov 1997) |
| C value paradox | <molecular biology> Comparison of the amount of DNA present in the haploid genome of different organisms (the C value) reveals two problems: the value can differ widely between two closely related species and there seems to be far more DNA in higher organisms than could possibly be required to code for the modest increase in complexity. (21 May 1997) |
| half-value layer | <radiobiology> The thickness of a specified material (usually a specific absorber), which attenuates a beam of radiation so that the exposure rate or absorbed dose rate at a specified point is reduced by half. (20 Sep 2002) |
| predictive value | An expresion of the likelihood that a given test result correlates with the presence or absence of disease. A positive predictive value is the ratio of patients with the disease who test positive to the entire population of individuals with a positive test result; a negative predictive value is the ratio of patients without the disease who test negative to the entire population of individuals with a negative test. (05 Mar 2000) |
| predictive value of tests | In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test. (12 Dec 1998) |
| present value | The worth of future receipts or costs expressed in current value. To obtain present value, an interest rate is used to discount future receipts or costs. (05 Dec 1998) |
