Precision using natural inclusions for the major gas species measured is generally 2 5%, these being dependent on summed errors derived from instrument noise, linearity of the mass spectrometer, uncertainty of standards, blanks, interferences, and measurement of sensitivity factors.
The daily measurement of sensitivity demonstrated a lower but similar pattern across the assessed data sets.
Analytical validation refers to the measurement of sensitivity and reproducibility of the proposed assay/technology.
In the last 10 15 years, preclinical research methodologies have increased crucially regarding measurement of sensitivity and specificity.
In addition, the AUC, a comprehensive measurement of sensitivity and specificity, is improved markedly from 0.56 to 0.8.
DNA samples were then processed using quantitative qPCR to provide quantitative assessment, as well as measurement of sensitivity and specificity.
Measurement of sensitivities of filamentous fungi to the structural analogs of benzaldehyde was based on percent radial growth of treated compared to control fungal colonies (Test concentrations: 0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0 mM).
In this case, all of the measurements of sensitivity, specificity, precision, F-measure, and ROC for seizure class are 99, 99, 98.5, 98.5, and 99.4 %, respectively The total classification accuracy is 95.33 %, and the other performance parameters (sensitivity, specificity, precision, F-measure, and ROC) are at least 92 % for both healthy and seizure-free classes.
We examine how properties of the sensor test system can introduce errors into measurements of sensitivity, reproducibility and response time of SMO sensors.
To obtain more accurate measurements of sensitivity and specificity, we determined the observed sensitivity and specificity of stress (exercise and dipyridamole) single photon emission computed tomographic (SPECT) thallium testing for the detection of coronary artery disease by angiography, and then applied previously published equations to correct for work-up bias.
Processing of DNA samples using qPCR provided quantitative assessments, as well as measurements of sensitivity and specificity.
