How does a doctor diagnose the flu?

Question

What tests are performed? What samples need to be taken?

Answer 1

Since this is not my area of expertise, I searched Google under the key words "flu diagnosis" to get this:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
