Sensitivity and specificity

ist group (n= 25) received US test and the second group (n=22) received MRI test. The result of the study, 96 percent specificity of US group, five patients with a size of smaller than 5mm lesion related to MN and with only one false negative outcome with 3.5 mm lesion as based on the microscopic analysis (Fazal et al.,2012). The results of MRI among 22 patients with 88% sensitivity with a lesion of 6.6 mm with false negative of 3 patients with 6 mm of a lesion. Therefore, Faizal et al.(2012)…

was less cost-effective than other currently available screening options, mainly gFOBT and FIT. Carcino-embryonic antigen (CEA), a conventional cancer marker that has been considered as a blood-based screening option, exhibited limited sensitivity and specificity [131]. Ladabaum et al [130] compared screening with a methylated Septin 9 DNA plasma assay (SEPT9) to screening with gFOBT, FIT, sigmoidoscopy and colonoscopy. Like the overall stool-based DNA testing, SEPT9 was cost-effective compared…

identification of MS was improved by 2 months prior to 1 month (2005) detected by MRI and will also be useful to identify onset of disease. As detection of MS was increasing , and to prove that the above hypothesis were true, specificity was found to be 86% and sensitivity…

Antibiotic sensitivity is the susceptibility of bacteria to antibiotics. Susceptibility can vary within bacteria of the same species due to different strains; with some strains being more resistant than others. Antimicrobial resistance is the ability of a microorganism to survive and multiply in the presence of an antimicrobial agent that would normally inhibit or kill this species of microorganism. Antibiotic susceptibility tests are done in order to determine, which specific antimicrobials…

of no-VRE were conducted by triple Taqman probe real-time PCR collected from 2005 to 2015 in China. Results: When detect the VRE strains, the sensitivity, specificity, PPV and NPV of triple Taqman probe real-time PCR were 99.6%, 100%, 100% and 98.9%, respectively. When differentiate among three genotypes of vanA, vanB and vanM VRE, the sensitivity, specificity, PPV and NPV of the triple Taqman probe real-time PCR were…

Advancement of medical imaging modalities, such as ultrasound, has significantly helped researchers and health professionals visualise dimensional and morphologic changes within the tendon, such as may occur with overuse injuries amongst athletes. Both Magnetic Resonance Imaging (MRI) and ultrasound have unique benefits and limitations. MRI may be better suited where there is a need for a differential diagnosis while ultrasound can be used to demonstrate active and passive movements in real…

giving the results such as suggesting that a child may have a developmental delay, requires adequate communication and resources to be available to complete additional testing as needed to decrease stress on the family and patient. Lastly, specificity and sensitivity are both crucial to developmental delays and abnormalities to be corrected or adapt to alternate ways of living, which are equally…

another rather than focus on separation from normal subjects (Millon et al., 2006). Craig investigated sensitivity and specificity of Scales T (Drug Dependence) and Scale B (Alcohol Dependence) with 164 substance use inpatients. Craig reported a significant improvement over previous versions of the MCMI. The study indicated a greater sensitivity to diagnosing substance misuse but a reduced specificity (Craig, 1997). Additionally, Craig and Olson (1997) investigated the ability of the MCMI to…

It has been used in detecting and quantifying specific antibodies and antigens in different samples7. ELISA has the advantages of high sensitivity and strong specificity due of the selectivity and affinity of monoclonal antibodies. Competitive ELISA is used for detection of the small molecules and for its high sensitivity. Electrochemical immunosensor combines the advantages of immunoassay and electrochemical detection. Electrochemical detection has the advantages of miniaturization…

Principle: By using a scanning device to detect positron (subatomic particles) emitted by the radionuclide in the organ or tissue being examined. A PET scan uses a radioactive drug (tracer) to show this activity. The radioactive drug may be injected, swallowed or inhaled, based on which organ or tissue is being evaluated by the PET scan. Positrons are emitted by a breakdown of the radionuclide then gamma ray is created and the scanner then detects the gamma rays a computer analyses the gamma…
