I am not a nurse, yet. But i recently had to deal with the push for testing. My youngest had strep and a couple of days later my oldest was complaining of a sore throat. I called to notify the school's office that she would be absent in order to be seen. They told me that she needed to be there for testing. When I asked about their strep policy, they informed me that technically their policy only concerned diagnosed strep. I was amazed, especially since my youngest had already been diagnosed only a few days before then.
