Yes, if you read it carefully, it says "several days". I think most people searching will see 24 hours, and then click away without analyzing so carefully.

Several days is still far off from 7-10 days.

The point is, I'd much rather see a link to my county's official Covid-19 testing information site, rather than an arbitrary outdated snippet pulled from a WebMD article. Google's "best guess" answer is often pretty bad.
