The Culture Test for Strep Throat Takes a Day or Two

The culture test for strep throat takes a day or two but is 95% sensitive and accurate, so it's better than the rapid test. Why do doctors do both?

A) So they can charge you more.
B) Because the rapid test is less accurate, but the bacteria is so contagious it's best to get the patient started on antibiotics as quickly as possible, even if it turns out they don't have strep.
C) Because it's okay to use antibiotics, even when you don't really need them.
D) Because strep throat is often deadly if left untreated for more than 24 hours.
E) Because the culture test is less accurate but the bacteria is so contagious it's best to get started on antibiotics as quickly as possible, even if it turns out the patient doesn't have strep.
