SINGAPORE (Bernama): A total of 33 cases that previously tested positive for Covid-19 by a laboratory in the republic actually turned out to be false positives due to a calibration problem of the device with one of the test kits.
“Subsequent tests at the National Public Health Laboratory confirmed that these were negative cases,” the Republic’s Ministry of Health said in a statement on Sunday night (May 10).
The ministry said no false negative results were found from its review.
He said he has taken immediate steps to rectify the situation, adding that the laboratory has stopped all testing and is working to resolve the calibration problem.
In addition, the ministry said that there were two results that were equivocal and that were later verified as negative when the test was performed again.
As on Sunday, Singapore had 23,336 Covid-19 cases, with 425 cases discharged from hospitals or community isolation facilities here, bringing the total discharges to 2,721.
There are currently 1,097 confirmed cases still in hospitals with 22 in the intensive care unit.
The ministry said 19,498 cases with mild symptoms, or clinically good, but still positive for Covid-19, have been isolated and cared for at community facilities.
The new cases involved one case imported from Qatar, four cases in the community, 11 foreign workers residing outside the dormitories and 860 foreign workers in dormitories.
Singapore has recorded 20 deaths since the first two reported on March 21 – Bernama
