Should CNA be tested for health problems

Bosch has developed an automated rapid corona test

The result should be there after just two and a half hours - Bosch Healthcare Solutions, together with the Northern Irish company Randox Laboratories, has presented a rapid test for COVID-19, which should be available in Germany from April.

The epidemic that the SARS-CoV-2 coronavirus triggered poses major challenges for almost the entire world. The health systems in particular are of course exposed to very great strains, but the economy will also find it difficult to recover from the current restrictions. How quickly this happens and how well the population survives the pandemic in terms of health essentially depends on how effectively the further spread of the virus can be controlled. For this it is crucial to identify sick people quickly and reliably in order to be able to isolate them if necessary.

Bosch has now fine-tuned its test and released a new version. Read on here

However, that is exactly what is currently a problem. Anyone who has symptoms currently has to wait around one to two days in Germany before finding out the result. One reason for this is the time-consuming procedure: Since there have been no rapid tests up to now, the throat swab samples are usually sent to a laboratory. The transport is associated with a high loss of time. In addition, the next problem is foreseeable - the laboratories have already reached their limits. With an increasing number of infections, further testing options are urgently needed. The new rapid test that Bosch subsidiary Bosch Healthcare Solutions and Randox Laboratories Ltd. developed is intended to eliminate these difficulties in one fell swoop and offer a quick and reliable diagnosis.

The analyzer automatically processes the sample in a cartridge

The COVID-19 rapid test is intended for medical facilities and could, for example, be used in doctor's offices, hospitals and health centers. The basis is the Vivalytic analyzer from Bosch Healthcare Solutions. For use, the medical staff takes a sample from the patient's nose or throat using a swab and puts it into a cartridge. It already contains all reagents that are required for the test. This cartridge is only inserted into the Vivalytic analyzer; the evaluation is fully automatic and takes about two and a half hours. If the spatial possibilities for an isolated stay are available, the patients can in principle wait for the result - and, if necessary, be quarantined afterwards.

According to Bosch, laboratory tests have confirmed that the rapid test identifies SARS-CoV2 with an accuracy of more than 95% and meets the quality standards of the World Health Organization (WHO). At the same time, the application is so easy that it is not necessary to specially train the staff for it. A single device can test up to ten samples in a 24 hour period. “In the fight against the coronavirus, time is one of the decisive factors. Reliable, fast diagnosis directly on site without detours - that is the great advantage of our solution, which for us is also an example of technology for life, ”says Volkmar Denner, Chairman of the Board of Management of Robert Bosch GmbH.

Test for 9 other respiratory diseases is possible

Bosch developed the rapid test within 6 weeks and gave it an additional plus point: One sample can be examined in parallel for nine other respiratory diseases, such as influenza A and B.

“What is special about the Bosch test is that the differential diagnosis also saves the doctors the time for further tests, they quickly receive a well-founded diagnosis and can use it to initiate a suitable therapy more quickly,” says Marc Meier, Managing Director of Bosch Healthcare Solutions GmbH.

The test device should come on the market in Germany in April. This is followed by other international markets.

At the same time, Bosch is examining how it would be possible to support doctors and nursing staff in medical facilities so that they can be tested as soon as possible. The aim is to ensure that qualified personnel remain operational for a long time without presenting a risk of infection for others.
