No. The point is, COVID-19 testing kit is in extreme short supply everywhere in the world right now given most countries are locked down and the viral outbreak patients are growing at an exponential rate, the next reliable way to diagnose COVID-19 for clinicians without testing kits is to use CT (which gets results fast and inexpensive and the equipment is universally accessible in every hospital) scans and find some patterns, which is exactly what doctors in Wuhan did during the early phase of the outbreak[1].
