In medicine and medical statistics, the gold standard, criterion standard, [1] or reference standard [2] is the diagnostic test or benchmark that is the best available under reasonable conditions. [3] It is the test against which new tests are compared to gauge their validity, and it is used to evaluate the efficacy of treatments. [1]
[1] [2] In clinical practice, verification bias is more likely to occur when a preliminary diagnostic test is negative. Because many gold standard tests can be invasive, expensive, and carry a higher risk (e.g. angiography, biopsy, surgery), patients and physicians may be more reluctant to undergo further work-up if a preliminary test is negative.
However, electron microscopy is highly versatile due to its ability to analyze any type of sample and identify any type of virus. Therefore, it remains the gold standard for identifying viruses that do not show up on routine diagnostic tests or for which routine tests present conflicting results. [7]
In addition, there is an optional L-line for wakeup. The data rate is between 1.2 and 10.4 kilobaud, and a message may contain up to 255 bytes in the data field. [1] When implemented on a K-line physical layer KWP2000 requires special wakeup sequences: 5-baud wakeup and fast-initialisation. Both of these wakeup methods require timing critical ...
[1] Antibiotic sensitivity testing is also conducted at a population level in some countries as a form of screening. [4] This is to assess the background rates of resistance to antibiotics (for example with methicillin-resistant Staphylococcus aureus), and may influence guidelines and public health measures. [4]
Gold Standard Laboratories or GSL was an independent record label which was founded in 1993 in Boulder, Colorado by Sonny Kay. In 2000, it was relocated to San Diego, California, United States, and two years later, to Los Angeles. It was headquartered in L.A. until closing its doors on October 29, 2007. [1] [2]
AIDA64 is a system information, diagnostics, and auditing application developed by FinalWire Ltd (a Hungarian company) that runs on Windows, Android, iOS, ChromeOS, Windows Phone, Sailfish OS, Ubuntu Touch and Tizen operating systems. It displays detailed information on the components of a computer.
[1] [8] The third edition added a "Do Not Do" recommendation, for tests deemed no longer useful. [2] Some tests such as a quick test for malaria, do not require a laboratory, a health care setting or professional, or electricity. [10] For each group of tests, the EDL specifies the test's name, purpose, assay format and type of specimen. [6]
