Funny thing is that it sounds lihe the doc at urgent care is the 'old-fashioned' kind to have just looked at your throat ... cause, my dear, he was not just looking at the throat, he was also getting a good whiff of your breath! And strep breath is ICKY! I don't need the test to tell me when little one here has it - that breath smell is it (and seems to come early on).
The reason they do the stupid test is cause the stupid insurance won't pay w/o it -- that's from my fav old pedi many years ago when one of my own kids had it and he said we both know what it is, but if he didn't do that stupid test, the insurance wouldn't pay ...grrrr!! (so it just cost more $$ - insurance could've saved themselves)
