Validation of TaqMan-Based Assays for Specific Detection and Differentiation of Wild-Type and Neethling Vaccine Strains of LSDV.
able to distinguish Neethling-based LAV s and wild-type LSDV were developed. Upon validation, both assays were shown to have high sensitivity and specificity with a diagnostic performance comparable to ...
Selection and use of reference panels: a case study highlighting current gaps in the materials available for foot and mouth disease.
are required. These are to: reduce bias in estimates of the diagnostic sensitivity and inter-serotypic specificity of tests used to detect diverse strains of FMD virus (FMDV), provide bio-safe positive ...
A molecular assay for rapidly distinguishing the AviPro SALMONELLA VAC T vaccine strain from wild-type field isolates
This molecular test is able to distinguish both Salmonella ser. Typhimurium types with 100% sensitivity and specificity within one working day. Health Topics: Salmonellosis Salmonellose Salmonellose ...
Selection and use of reference panels: a case study highlighting current gaps in the materials available for foot and mouth disease
an example, this review highlights four specific areas where new reference reagents are required. These are to: reduce bias in estimates of the diagnostic sensitivity and inter-serotypic specificity of ...
Validation strategy of a bioinformatics whole genome sequencing workflow for Shiga toxin-producing Escherichia coli using a reference collection extensively characterized with conventional methods
a validation strategy specifically adopted to WGS, we demonstrated high performance with repeatability, reproducibility, accuracy, precision, sensitivity and specificity above 95 % for the majority of all ...
Validity of self-reported mammography uptake in the Belgian health interview survey: selection and reporting bias.
validity is significantly affected by both selection bias {relative size = 8.93% [95% confidence interval (CI): 3.21-14.64]} and reporting bias [relative size = 8.22% (95% CI: 0.76-15.68)]. Sensitivity was ...
Comparing health insurance data and health interview survey data for ascertaining chronic disease prevalence in Belgium.
both data sources were compared. Agreement was measured using sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) assuming BHIS data as gold standard. Kappa ...
Deep amplicon sequencing for culture-free prediction of susceptibility or resistance to 13 anti-tuberculous drugs.
isolates, the assay predicted 92.2% of 2369 first- and second-line phenotypes, with a sensitivity of 95.3% and specificity of 97.4%. Fifty-six of 69 (81.2%) residual discrepancies with phenotypic results ...
Use of Whole Genome Sequencing Data for a First in Silico Specificity Evaluation of the RT-qPCR Assays Used for SARS-CoV-2 Detection.
Polymorphism, Single Nucleotide Real-Time Polymerase Chain Reaction RNA Replicase RNA, Viral Sensitivity and Specificity whole genome sequencing Abstract: The current CO ronaVIrus Disease 2019 (COVID-19) pandemic ...
Overview of diagnostic tools for Capripox virus infections.
purpose. The need for high throughput, high specificity/sensitivity and the capability for differentiating field virus strains from vaccine strains drives the development of new and better assays preferably ...
