Some studies of a commercial PCR test for influenza showed a relatively low sensitivity (∼75%); the authors suggest the use of a more sensitive reference test to confirm negative results.
In an earlier version, the bill had a politically sensitive reference to bullying based on sexual identity or orientation.
Visual inspection of the heat map suggests that the portion of the cerebellum and vermis superior to the horizontal fissure is the most sensitive reference region.
Moreover, thanks to its peculiar transduction principle and structure, the device sensitivity can be easily tuned by acting on geometry-related parameters of the device itself, introducing an interesting alternative approach for the realization of highly sensitive, reference-less, and low-cost devices for a wide range of bio-sensing applications.
In order to show further improvements in imaging, we need a more sensitive reference standard.
The authors claim that the PPV is even higher when a more sensitive reference test was used.
These studies also used the least sensitive reference standard which may explain that results of Models 4 and 5, both allowing for imperfect reference standards, were similar.
An index test compared against a more sensitive reference test (microscopy with multiple measurements) may have higher specificity because the number of false-positives will be low.
Three isolates, 29, 7, and 15 had significant yet moderate effect on TER similar to the antibiotic sensitive reference strains ATCC 27853, PA01, and PA190.
A less sensitive reference test to diagnose GERD reduces the number of GERD patients and as a result overestimates the sensitivity and underestimates the specificity of a symptom.
An index test compared against a more sensitive reference test (higher quality) may have higher specificity because the number of false-positives will be low.
