I remember an article early in the outbreak that Chinese doctors found the most reliable diagnosis comes from CT scans. Test was merely the first filter. They tuned the settings to increase scan speed at the cost of resolution and setup a process to scan up to 200 patients a day per scanner. I wonder if this is still best practice that other countries aren't adopting. On the other hand I expect tests to have improved since the early days. There's also the consideration China simply had more CT scanners that could be mobilized to Wuhan which makes this less practical elsewhere.
