Sensitivity and specificity

points for mild, moderate and severe anxiety, respectively. In general, GAD-7 has a sensitivity of 89% and specificity of 82% for generalized anxiety disorder (GAD). Also, it is accurate at measuring three other common anxiety disorders such as panic disorder (sensitivity 74%, specificity 81%), social anxiety disorder (sensitivity 72%, specificity 80%) and post-traumatic stress disorder (sensitivity 66%, specificity 81%) (Kroenke, Spitzer, Williams, Monahan, &…

were found for the LIAISON CLIA and LC-MS/MS method. Then followed the RIA. The Immulite CLIA showed the highest overall values and thus the lowest precision. A detailed list of all calculated variation coefficients is provided in Table 1 (A). Sensitivity The limit of blank (LoB), limit of detection (LoD) and limit of quantification (LoQ) were determined for all methods. The RIA proved to be the most analytically sensitive method, followed by LC-MS/MS. The LIAISON CLIA proved to be less…

With the empty can test, pain decreases the specificity of the overall test- pain can even be present with an intact rotator cuff.5 Additionally, there can be a 20% reduction in strength that cannot be detected by the tests if the patient is stronger than the clinician. In…

community. (Nlm.nih.gov, 2014) (Masterton et al., 2008) state that “The diagnosis of HAP cannot only be made on the clinical criteria as the clinical signs and symptoms overlap between pneumonia and other forms of sepsis. To improve the diagnostic sensitivity the following should be taken into account: • The presence of a fever (core temperature of 38ºC) • Blood leukocytosis (10 000…

Introduction/Purpose Ahmad, et al investigated the moving patellar apprehension test or MPAT to discover its efficacy in diagnosing patellar instability. They focus on the moving patellar apprehension test examining its sensitivity, specificity, and positive and negative predictive values in patellar instability particularly pertaining to lateral patellar subluxation/dislocation. Patellar instability occurs mainly in the adolescent population and can be caused by a variety of anatomical…

DSM-III-R. After this chart review, 46 patients were found to suffer from major depressive disorder. This was then compared to the GDS administered at the beginning of their admission. Lesher and Berryhill found that the GDS had a sensitivity of .91 and a specificity of .54, making the overall percentage of the GDS forming the proper diagnosis 78% (p. 259). Based on these findings, Lesher and Berryhill concluded that the GDS is “very efficient and effective measure for screening of…

scoring criteria for malignancy was reduced from four (as described in original paper) to three in 1989 when cases with lower Weiss scores were noted to behave in a malignant fashion. Unfortunately, cut-off at three still does not achieve a sensitivity and specificity of 100%. This is reflected in case 2 where despite scoring only two criteria, concerns were raised given that endocrine neoplasms do not always correlate with the histopathological features. Given the large tumour size and weight…

from the chiral impurity was observed at 1% level of the main peak. The developed method was found efficient for determination of the enantiomeric purity of the drugs in pharmaceutical preparation. Good resolution between isomers, high detector sensitivity and baseline stability were essential for the detection of trace amounts of R isomers at a level of (1%) of the main peak. The high detector…

prospectively evaluate the sensitivity and specificity of the real-time sonoelastography together with B-mode US for distinguishing between benign and malignant breast lesions. Methods: The study was conducted on 20 patients with 36 lesions, each patient was subjected to complete history taking, thorough clinical examination. Then all patients had conventional US and elastography while only in 17 patients mammography was done. Results: Among the 20 patients, sensitivity and specificity of the…

indicative of delirium; higher scores indicate higher severity of delirium. 22, 28-29 The DRS-R-98 total score distinguishes delirium from dementia, schizophrenia, depression, and other medical illness during blind rating, with sensitivity ranging from 91% to 100%, and specificity ranging from 85% to 100%, depending upon the cut-off score chosen. 22,…
