  2. Sensitivity and specificity - Wikipedia

    en.wikipedia.org/wiki/Sensitivity_and_specificity

    The 'worst-case' sensitivity or specificity must be calculated in order to avoid reliance on experiments with few results. For example, a particular test may easily show 100% sensitivity if tested against the gold standard four times, but a single additional test against the gold standard that gave a poor result would imply a sensitivity of ...

  3. False positives and false negatives - Wikipedia

    en.wikipedia.org/wiki/False_positives_and_false...

    The specificity of the test is equal to 1 minus the false positive rate. In statistical hypothesis testing, this fraction is given the Greek letter α, and 1 − α is defined as the specificity of the test. Increasing the specificity of the test lowers the probability of type I errors, but may raise the probability of type II errors (false ...

  4. Methods to investigate protein–protein interactions - Wikipedia

    en.wikipedia.org/wiki/Methods_to_investigate...

    Each of the approaches has its own strengths and weaknesses, especially with regard to the sensitivity and specificity of the method. [1] A high sensitivity means that many of the interactions that occur are detected by the screen. A high specificity indicates that most of the interactions detected by the screen are occurring in reality.

  5. Sensitivity - Wikipedia

    en.wikipedia.org/wiki/Sensitivity

    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

  6. Gold standard (test) - Wikipedia

    en.wikipedia.org/wiki/Gold_standard_(test)

    A hypothetical ideal "gold standard" test has a sensitivity of 100% concerning the presence of the disease (it identifies all individuals with a well-defined disease process; it does not have any false-negative results) and a specificity of 100% (it does not falsely identify someone with a condition that does not have the condition; it does not have any false-positive results).

  7. Chromatin immunoprecipitation - Wikipedia

    en.wikipedia.org/wiki/Chromatin_immunoprecipitation

    Testable antibody specificity Better antibody specificity as target protein naturally intact. Better chromatin and protein revery efficiency due to better antibody specificity Disadvantages: Inefficient chromatin recovery due to antibody target protein epitope disruption May cause false positive result due to fixation of transient proteins to ...

  8. Evaluation of binary classifiers - Wikipedia

    en.wikipedia.org/wiki/Evaluation_of_binary...

    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).

  9. Bradford protein assay - Wikipedia

    en.wikipedia.org/wiki/Bradford_protein_assay

    The entire experiment is done at room temperature. The Bradford protein assay can measure protein quantities as little as 1 to 20 μg. [14] It is an extremely sensitive technique. The dye reagent is a stable ready to use product prepared in phosphoric acid. It can remain at room temperature for up to 2 weeks before it starts to degrade.
