Sensitivity and specificity of standardised allergen extracts in skin prick test for diagnoses of IgE-mediated respiratory allergies

Clinical and Translational Allergy, 2019
BackgroundSkin prick tests (SPTs) are essential for the diagnosis of IgE-mediated allergy and are influenced by extract quality, biological potency and concentration of allergen.MethodsIn this open multicentre study 431 patients, aged 18–64 years were ...

Determination of a cutoff for noise sensitivity: Psychometric evaluation of the Turkish Noise Sensitivity Questionnaire (Tr-NoiSeQ)

Noise and Health, 2022
Context: There is a need for a clear cutoff to use noise sensitivity (NS) scale as a prediagnostic tool in research and clinical use. Aims: Noise sensitivity questionnaire (NoiSeQ) was adapted into Turkish language (Tr-NoiSeQ); validity and reliability ...

High-sensitivity cardiac troponin T and copeptin assays to improve diagnostic accuracy of exercise stress test in patients with suspected coronary artery disease [PDF]

, 2014
Background: The average diagnostic sensitivity of exercise stress tests (ESTs) is lower than that of other non-invasive cardiac stress tests. The aim of the study was to examine whether high-sensitivity cardiac troponin T (hs-cTnT) or copeptin ...

The Hippocampal Film Editor: Sensitivity and Specificity to Event Boundaries in Continuous Experience

Journal of Neuroscience, 2018
The function of the human hippocampus is normally investigated by experimental manipulation of discrete events. Less is known about what triggers hippocampal activity during more naturalistic, continuous experience.

Bayesian estimation of diagnostic accuracy of fecal culture and PCR-based tests for the detection of Salmonella enterica in California cull dairy cattle. [PDF]

, 2020
Epidemiological studies of low prevalence disease problems are often hindered by the high cost of diagnostic testing. The objective of this study was to evaluate PCR screening of both individual and pooled fecal samples from culled dairy cows for the ...

A33 shows similar sensitivity to but is more specific than CDX2 as an immunomarker of colorectal carcinoma [PDF]

, 2017
Aims: CDX2 is widely used as a sensitive and specific immunomarker for colorectal carcinoma (CRC) but neither this sensitivity nor specificity is absolute. This study is the first known comparison of CDX1 and A33 against CDX2 as immunomarkers for CRC.

The sensitivity and specificity of platelet autoantibody testing in immune thrombocytopenia: a systematic review and meta‐analysis of a diagnostic test

Journal of Thrombosis and Haemostasis, 2019
Essentials The diagnosis of ITP is based on a platelet count < 100 × 109 L−1 and exclusion of other causes. There are no standard tests or biomarkers to diagnose ITP. The sensitivity of platelet autoantibody testing is low (53%). The specificity is high (

Factors Associated with Marburg Hemorrhagic Fever: [PDF]

, 2010
Background. Reliable on-site polymerase chain reaction (PCR) testing for Marburg hemorrhagic fever (MHF) is not always available. Therefore, clinicians triage patients on the basis of presenting symptoms and contact history.

Foundational Statistical Principles in Medical Research: Sensitivity, Specificity, Positive Predictive Value, and Negative Predictive Value

Medicina, 2021
Sensitivity, which denotes the proportion of subjects correctly given a positive assignment out of all subjects who are actually positive for the outcome, indicates how well a test can classify subjects who truly have the outcome of interest. Specificity,

Coexistence of critical sensitivity and subcritical specificity can yield optimal population coding

, 2017
The vicinity of phase transitions selectively amplifies weak stimuli, yielding optimal sensitivity to distinguish external input. Along with this enhanced sensitivity, enhanced levels of fluctuations at criticality reduce the specificity of the response.
