There are different definitions within laboratory quality control, wherein "analytical sensitivity" is defined as the smallest amount of substance in a sample that can accurately be measured by an assay (synonymously to detection limit), and "analytical specificity" is defined as the ability of an assay to measure one particular organism or ...
The sensitivity of a loudspeaker is usually expressed as dB / 2.83 V RMS at 1 metre. [citation needed] This is not the same as the electrical efficiency; see Efficiency vs sensitivity. This is an example where sensitivity is defined as the ratio of the sensor's response to the quantity measured.
They use the sensitivity and specificity of the test to determine whether a test result usefully changes the probability that a condition (such as a disease state) exists. The first description of the use of likelihood ratios for decision rules was made at a symposium on information theory in 1954. [ 1 ]
The relationship between sensitivity and specificity, as well as the performance of the classifier, can be visualized and studied using the Receiver Operating Characteristic (ROC) curve. In theory, sensitivity and specificity are independent in the sense that it is possible to achieve 100% in both (such as in the red/blue ball example given above).
Sensitivity (physiology), the ability of an organism or organ to respond to external stimuli Sensory processing sensitivity, a personality trait in humans; Sensitivity and specificity, statistical measures of the performance of binary classification tests; Allergic sensitivity, the strength of a reaction to an allergen
Sensitivity can also be referred to as the recall, hit rate, or true positive rate. It is the percentage, or proportion, of true positives out of all the samples that have the condition (true positives and false negatives). The sensitivity of a test can help to show how well it can classify samples that have the condition.
Antibiotic sensitivity testing or antibiotic susceptibility testing is the measurement of the susceptibility of bacteria to antibiotics. It is used because bacteria may have resistance to some antibiotics.
Assay sensitivity is a property of a clinical trial defined as the ability of a trial to distinguish an effective treatment from a less effective or ineffective intervention. [1] Without assay sensitivity , a trial is not internally valid and is not capable of comparing the efficacy of two interventions.
