  2. Sensitivity and specificity - Wikipedia

    en.wikipedia.org/wiki/Sensitivity_and_specificity

    Sensitivity and specificity values alone may be highly misleading. 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 ...

  3. Bradford protein assay - Wikipedia

    en.wikipedia.org/wiki/Bradford_protein_assay

    The Bradford protein assay (also known as the Coomassie protein assay) was developed by Marion M. Bradford in 1976. [1] It is a quick and accurate [2] spectroscopic analytical procedure used to measure the concentration of protein in a solution.

  4. Cardiac stress test - Wikipedia

    en.wikipedia.org/wiki/Cardiac_stress_test

    Sensitivity refers to the percentage of individuals with the condition correctly identified by the test, while specificity denotes the percentage of individuals without the condition correctly identified as not having it. [21] The nuclear stress test exhibits a sensitivity of 81% and a specificity ranging from 85 to 95%. [22]

  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. Likelihood ratios in diagnostic testing - Wikipedia

    en.wikipedia.org/wiki/Likelihood_ratios_in...

    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 ]

  7. Assay sensitivity - Wikipedia

    en.wikipedia.org/wiki/Assay_sensitivity

    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.

  8. Myasthenia gravis - Wikipedia

    en.wikipedia.org/wiki/Myasthenia_gravis

    Applying ice for 2–5 minutes to the muscles reportedly has a sensitivity and specificity of 76.9% and 98.3%, respectively, for the identification of MG. Acetylcholinesterase is thought to be inhibited at the lower temperature, which is the basis for this diagnostic test. This generally is performed on the eyelids when ptosis is present and is ...

    en.wikipedia.org/wiki/Talk:Sensitivity_and...

    The article states (under the "Sensitivity" and "Specificity" sections respectively) that "negative results in a high sensitivity test are used to rule out the disease" (referred to by the mnemonic "SNOUT" later in the article) and that "a positive result from a test with high specificity means a high probability of the presence of disease ...
