Smart PhoneBosch has adopted an innovative approach to the Antibody test against Covid-19. Besides, they had developed the screening for a swab method. Even more, the company designed these kits to produce results in less than two and a half hours.

Bosch’s Solution

The company runs on Bosch’s analytical device. Moreover, it is one of the world’s automated molecular diagnostics. Even more, all medical institutions can use it.

The Vivalytic check consists of an analyzer tool and test cartridges that suit. In each of the rounds, biological components are used. These components prove if a sample contains SARS-CoV-2 or nine other respiratory viruses. In turn, this removes the need for more examinations. Besides, this is ideal if you may not have Covid-19, but one of the other nine infections is present.

They became available in Germany in April, followed by other European markets. Bosch’s Coronavirus kits are one of the world’s first automated molecular checks. These are to determine a SARS-CoV-2 infection. These also identify nine other respiratory viruses within 2,5 hours. Hence, it is an antibody test.

How does it work?

One form of rapid diagnostics identifies antigens’ expression. These represent the viral proteins. It checks antigens produced by the disease. To do that, though, doctors need a sample from a person’s respiratory tract. So now, how can you know if the target is present in the example at appropriate amounts? It’s simple.

Furthermore, it attaches to unique antibodies attached to a paper strip. This paper strip is enclosed in a plastic casing. It produces a clearly recognizable signal, usually within 30 minutes. The observed samples are released only while the pathogen is actively replicating. Thus, doctors use such measures to diagnose severe or early infection.

Are these kits good?

How well the experiments perform depends on many factors. These factors include the period from disease initiation and the concentration of the pathogen in the tissue. Others are the consistency of a person’s collected sample and how it is handled. More so, the exact composition of the reagents in the test kits represents another factor. Let’s consider the experience with these kits for other respiratory diseases. For example, influenza. In this case, Influenza patients have similar concentrations in respiratory samples to Covid-19. Plus, the sensitivity of these examinations could vary from 34 to 80%.


Based on this knowledge, these kits may miss half or more of infected patients. Besides, it depends on the category of patients taking it. These urgently need further study to understand whether they are accurate. Also, false-positive results represent checks indicating a person is infected when they are not. Such results may occur if the strip’s antibodies still identify pathogens other than Coronavirus.

A good example here is humans that trigger the common cold. Are you planning to use an antibody test? Or do you need acceptable results? You may use them as per your Doctor’s permission. After all, they help to easily recognize patients who are more likely to receive Covid-19. It ends up minimizing or removing the need for a costly molecular examination.

Lastly, we’ve limited available data on these kits. As a result, WHO currently does not recommend the use of this method. Thus, we need more research on their performance and potential diagnostic benefit.
