Since when is strep throat swabbed in the NOSE??

I had to take my 3 year old son to the hospital where I work for a rapid strep test the other day. I am a nurse on the Pedi unit but we got the test down in Outpatient. He was actually have Flu, RSV, and Strep tested. She swabbed each side of his nose and told me that the doctor's office would call me when they had results. I asked her if she was going to swab him for Strep and she said she did. I questioned the fact that she swabbed the nose and strep is in the throat. She told me that she did it correctly. I made some calls and we got it done...correctly. I wonder what would have happened if I had not been a nurse and didn't know the difference. The scariest part of the whole mess is that I think she was a nurse!
