The first testing kits for COVID-19 included a defect that contributed to weeks of delay in rolling out wider testing for the illness. The Department of Health and Human Services is looking into it.
The Centers for Disease Control and Prevention (CDC) manufactured the kits earlier this year and sent them to public health laboratories in all 50 states on Feb. 5. But some of the labs found inconclusive results being reported for specimens while validating the tests, causing all but a few states to wait until late February to test locally for samples.
