The use of rapid corona tests and home tests should become an important tool in the gradual reopening of society. Now that research has shown that the tests are good enough, ten large pilots will be launched in the short term to see whether the tests can be used in practice.
Eight of the pilots take place at educational institutions spread across the country, one at the fire brigade at Schiphol and the last at a company. All pilots are supervised from universities and hospitals. Pilots are already underway for teachers in primary education and one in secondary education.
As soon as the Medical Ethics Committee gives permission, the new pilots can actually start. It is expected that this permission will be given within a few days. Home tests, actually self-tests, are used in some of the pilots. For others, for example, also the breath test and the saliva test.
Two home rapid tests have recently been validated in a study by the Amphia Hospital in Breda and the GGD West Brabant in Tilburg. More than 3,200 people who came to a corona test street in Tilburg performed a home test after they had undergone a PCR test.
Half of that group the one home test, the other half the second home test from another brand. Both tests performed similarly. Article link https://www.news1.news/news/2021/02/ten-major-pilots-with-speed-and-home-test-to-try-out-usability.html
The specificity of the tests is high: they removed 99.4 percent of the cases that were also found positive with the PCR test. “If your self-test is positive, then you are really positive in almost all cases.”
The sensitivity is also relatively high at 78 percent”, says research leader Jan Kluytmans, medical microbiologist at the Amphia Hospital in Breda. “But you still have to deal with a number of false negative tests, people whose PCR test shows the virus but the home test does not.”
The false negative results of the self-test occurred mainly in the elderly, in people who indicated that they find self-testing difficult and when the number of virus particles was low.
“If the result of the home test is negative, students can go back to school relatively safely,” says Kluytmans, “but because of the false-negative results, they must continue to follow the rules of conduct. Keep their distance, wash hands, sneeze in the elbow and a mouth mask. wear where required. “
The number of false negative self-tests can be reduced by using the tests specifically in adolescents and young adults. Article link https://www.news1.news/news/2021/02/ten-major-pilots-with-speed-and-home-test-to-try-out-usability.html
The self-test is therefore ideally suited for students and older students. Furthermore, the number of false negative tests decreases by providing guidance in performing the self-test.
That is exactly what will happen in a pilot in Den Bosch in which 2500 students and pupils from Avans Hogeschool, HAS Hogeschool and Koning Willem I College will participate. From a room in the HAS, a university college for agricultural courses, students receive instructions via an image connection how to perform the self-test correctly.
The students receive the instruction in groups. After performing the test, they each wait 15 minutes for their own test result in a separate digital waiting room.
If the test is positive, the students must report this to the GGD and in quarantine. If the result is negative, they can go to school, but must therefore respect the corona rules there. Each self-test has a unique barcode. Students must enter their student number and test date before taking the test.
Armed with the barcode and the entered data, they then get access to the lessons for two days. So a negative test on Monday gives access to classes that same day and Tuesday. But before the lessons on Wednesday a new test has to be done.
Coordinator Carla Nagel hopes to start the pilot next week with 25 to 30 students. Article link https://www.news1.news/news/2021/02/ten-major-pilots-with-speed-and-home-test-to-try-out-usability.html
The following week 100 students will participate, the week after 500 and in the fourth week 2500 students and students. When they have all done four self-tests, the pilot is over and the results are analyzed.
The other pilots that will be launched shortly will take place in the regions of Groningen, Delft, Amsterdam, Nijmegen, Eindhoven, Utrecht and Rotterdam.
I hope you are in health and well.
