Japan to test 10,000 people for coronavirus antibodies english.kyodonews.net

KYODO NEWS - 6 minutes ago - 14:29 | All, Japan, CoronavirusJapan will test around 10,000 people for coronavirus antibodies starting from next month, as part of efforts to better understand the deadly infection, health minister Katsunobu Kato said Friday.
The tests come after the ministry last month conducted experimental screening for antibodies in donated blood in Tokyo and six prefectures in northeastern Japan, using test kits from five firms.
But experts noted some of the test kits could have provided false results.
In the screening, two samples of blood donated last year -- before coronavirus was confirmed in Japan -- tested positive for antibodies.
There are various types of antibody test kits available for COVID-19 but doubts remain over their accuracy.
