An internal CDC report obtained by NPR shows the CDC's original coronavirus test kits didn't just have a fundamental design flaw, but instructions sent to labs to run the test were problematic, too.

The new tests produce results completely at home within 15 minutes. Experts say they could be a 'game-changer' in helping people find out quickly if they need to isolate.
