Sensitivity and Specificity
Research News and Information
Definition of 'Sensitivity and Specificity'Measures for assessing the results of diagnostic and screening tests. Sensitivity represents the proportion of truly diseased persons in a screened population who are identified as being diseased by the test. It is a measure of the probability of correctly diagnosing a condition. Specificity is the proportion of truly nondiseased persons who are so identified by the screening test. It is a measure of the probability of correctly identifying a nondiseased person. (From Last, Dictionary of Epidemiology, 2d ed) |

Biopsy site for detecting Helicobacter pylori infection in patients with gastric cancer.
30 Nov 2009
BACKGROUND: Helicobacter pylori eradication is recommended in post-gastric cancer resection, but premalignant changes may prevent the detection of H. pylori. The aim of this study was to determine appropriate biopsy site for detecting H. pylori in ... Read more...

High-risk human papillomavirus (H-HPV) infection is strongly linked to cervical neoplasia, but its role in detecting glandular lesions (GLs) is unclear. In the cervix, carbonic anhydrase IX (CA-IX) is expressed in cervical neoplasia, but rarely in ... Read more...
