OTS - New study: Only reliable rapid corona tests make sense
2020. December 03. 13:01
Moers, Deutschland, 3 December, 2020 (APA/OTS) - More and more
manufacturers are bringing corona rapid tests onto the market. But
only if they provide reliable results does their use in the fight
against the pandemic makes sense. The Charité hospital in Berlin,
one of the largest university hospitals in Europe, has now reviewed
the performance of corona antigen rapid tests. The corona rapid
test from nal von minden GmbH proved to be particularly reliable.
The NADAL® COVID-19 Ag rapid test has already been used millions of
times throughout Europe during the corona pandemic and provides a
result within only 15 minutes.

Corona rapid tests are playing an increasingly important role.
In nursing homes, old people's homes and hospitals, they fulfil an
especially important function: infectious people can be detected
quickly and other people can be better protected against corona.
But how reliable are the test results? Researchers at the
Charité hospital in Berlin, led by virologist Prof. Christian
Drosten, have now examined both the specificity and sensitivity of
different tests. The specificity provides information on whether
all healthy people who have been tested are recognised as healthy.
The sensitivity indicates whether all sick people are also
recognised as sick.
The NADAL® COVID-19 Ag rapid test from nal von minden GmbH was
one of the best three tests evaluated: the specificity was 99.26
percent. In terms of sensitivity, the NADAL® COVID-19 Ag rapid test
also scored outstandingly well in the Charité study. Roland
Meißner, managing director of nal von minden GmbH: "We are pleased
about the confirmation of the very good quality of our rapid test.
"A total of 105 swab samples were analysed with the NADAL®
COVID-19 Ag rapid test in the Charité study". The swabs were
previously taken from the mouth or nasopharynx of patients, placed
in a tube with liquid transport medium and frozen at minus 20
degrees Celsius until the examination. Subsequently, comparative
tests were carried out in the laboratory in comparison to PCR.
The Charité's methodology differs slightly from clinical
studies conducted by nal von minden GmbH. Tobias Roth, biochemist
with a focus on virology: "We use the swabs directly on the antigen
test. Charité, on the other hand, put the swabs in a liquid
transport medium. As a result, the samples were diluted and the
results determined by a different evaluation method".
