relative specificity

rel·a·tive spec·i·fic·i·ty

the specificity of a medical screening test as determined by comparison with the same type of test (for example, specificity of a new serologic test relative to specificity of an established serologic test).

Results from FDS-NPs were used for calculation of relative accuracy (AC), relative specificity (SP), and relative sensitivity (SE) in comparison with results of the reference method.
The relative sensitivity and relative specificity of dianostic tests were calculated using the method described by Mcdiarmid and Hellstrom (1987).
Comparatively, 476, 205 and 79 samples were tested positive respectively by the immunochromato graphic method, has less sensitivity of 13% and a relative specificity of 12% compared to the ELISA method.
Analysis of the sensitivity and specificity for CIN 2 or higher samples using the Cervista test compared with the gold standard HC2 by noninferiority score tests showed that the performance of the new test was not inferior (relative sensitivity of 90%, T = 2.85, P = .002; and relative specificity of 98%, T = 2.75, P = .003).
At the 6-month posttreatment examination, HR-HPV testing has a significantly higher sensitivity than cytology, indicated by a relative sensitivity of 1.15 (95% CI 1.06-1.25), without decreasing the specificity (relative specificity 0.95, 0.88-1.02).
The relative specificity of PCT for bacterial infection is not necessarily a problem, however, because most infections associated with the development of severe sepsis are, in fact, bacterial.
A total of 56 serum samples with negative titres at a dilution of 1:100 against serovars Pomona, Icterohaemorrhagia, Canicola, Grippotyphosa, Autumnalis, Javanica and Hebdomidis were used to determine the relative specificity of the ELISA.
There was no difference between methods when high-grade or low-grade squamous intraepithelial lesion was used for calculating relative specificity. However, when ASCUS was used as a cutoff for an abnormal test result, liquid-based cytology was significantly less specific (0.91; 95% confidence interval, 0.84-0.98).
Because transaction costs are largely dependent on asset specificity, the choice between sell-off and layoff is impacted by the relative specificity of physical and human assets.
