(Bilgisayar) specificity
The probability, in a binary test, of a true negative being correctly identified
The proportion of condition positions at which are non-wildcard values
An operating characteristic of a diagnostic test that measures the ability of a test to exclude the presence of a disease (or condition) when it is truly not present Specificity is the proportion of nondiseased patients for whom there is a correctly negative test, expressed as the number of true negatives divided by the sum of true negatives + false positives (Contrast with sensitivity )
the state of being specific rather than general
how precise or exact a term or indexing language is in its ability to describe
the quality of being specific to a particular organism; "host specificity of a parasite
The specificity of a binder is the ability of its binding site to distinguish between the ligand to which the binder is specific and other compounds
The ability of a procedure to react only with the drugs or metabolites being tested and to exclude other substances A specific procedure is rarely positive if a substance is truly absent; thus, few false positive results will occur
a statistical measure of the accuracy of a screening test, i e , how likely a test is to label as negative those who do not have a disease or condition Contrast with sensitivity
The proportion of individuals free of the target condition in a population who are correctly identified by a screening test
The probability that patients without a particular disease, condition or injury will test negative for the problem by a particular test
is the proportion of people free of a disease who have a negative test Specificity
the proportion of true negatives detected by a diagnostic method
is the porportion of people free of a disease who have a negative test See also Calculating Sensitivity and Specificity
The chance of having a negative test result given that you do not have a disease (not to be confused with negative predictive value, which is the other way round)
(of a diagnostic test): the proportion of truly nondiseased persons, as measured by the gold standard, who are so identified by the diagnostic test under study
when searching databases, this refers to retrieving a smaller amount of information that is highly relevant, but possibly missing some good items that are slightly less relevant
the sensitivity that a detector has for an analyte compared to its sensitivity for another, potentially interfering, analyte
The percentage of cases predicted not to have the target outcome when the outcome is NOT PRESENT - eg negative in health
