What is the new Coronavirus can make a quick test?
A new COVID-19 Antigen Test provides similar to a pregnancy test, a first indication of an infection with the Coronavirus SARS-CoV-2 in just 15 minutes. Thus, it can be done quickly, an initial assessment of the how infectious is a Person at the time of the test. The Test could be Affected to an important tool for the staff in the health sector for the right way to deal with potential COVID-19-in order to protect themselves and other better-before other Transfers.
In facilities that come Ill contact with COVID-19 -, often lack the time and the Material to be challenging and time-intensive test systems. In the case of a first contact with a patient or a patient with a potential COVID-19-disease, it is unclear how contagious that Person is. A new Antigen Test may be within 15 minutes for this purpose, a first assessment. The Test was recently presented in the prestigious scientific journal “Frontiers in Medicine”.
SARS-CoV-2 detection in only 15 minutes
One of the most important means to stop the spread of the novel Coronavirus SARS-CoV-2, are fast, reliable and cost-effective diagnostic Tests at the Treatment site. European scientists have now developed a disposable Antigen Test that can produce in just 15 minutes a first detection of a COVID-19-infection to the forefront.
No quick diagnosis for COVID-19 available
Nearly four million infections and approximately 270,000 deaths worldwide are attributed to according to the Johns Hopkins University, in the meantime, the Coronavirus SARS-CoV-2 (Stand: 08. May 2020). The dark figure is clearly lying about it. A major Problem in the pandemic, the diagnosis of a novel pathogen is still. The currently available Tests are time-consuming and can need several days until the evaluation has occurred.
“The detection of virus infections in patients attending primary care centres, would enable the medical staff to quickly identify new outbreaks, and quarantine measures for patients with high virus boost and/or suspected cases to limit the spread of the epidemic,” write the authors of the current study.
How does a Antigen Test?
The Antigen Test looks for proteins on the surface of the Virus. The process is reminiscent of a pregnancy test. In the case of the test Person, a nose is carried out throat swab. This so-obtained body fluid with the test strip in contact. On the test strip antibodies respond to the Virus if it is present are located.
The company Coris BioConcept used for the production of the new Tests findings from previous virological research on SARS-CoV-1, which was for the SARS outbreak in 2002 and 2003. The two viruses are very similar, so the Test between SARS-CoV-1 and SARS-can’t distinguish CoV-2.
Pros and cons of the Antigen Tests
The researchers showed samples of about 300 COVID-19-Concerned that the Test works. However, it can provide absolute security. In 57.6 per cent of all cases, the Test showed, correctly, that a Person has been infected with SARS-CoV-2. The more infectious a Person, the more likely the Test is to hit. If a Person was not infected with SARS-CoV-2, was detected in 99.5 percent of the cases correctly.
In other words, The Test was able, in about six out of ten people COVID-19 detect evidence of infection. In individuals with higher viral load, even around seven out of ten infections could be detected.
Not as a stand-alone Test usable
Due to the high inaccuracy of the Antigen Test can not be used as a stand-alone Test, but must be used in the context of a broader testing strategy. However, the Test is superior in the speed, cost, and implementation of all other Tests and offer a quick aid to decision-making. In particular, countries with low and middle incomes, where only a few laboratories could benefit from the Test, conclude the researchers. (vb)
