Why Accurate Diagnosis Matters
Getting the right diagnosis helps you get the best care. For example, early treatment can lower the risk of serious problems. Also, knowing you have the flu can help you avoid spreading it to others.

How General Physicians Diagnose Influenza
Doctors use several steps to diagnose the flu. The process is simple but thorough. Let’s look at each step in detail.
Medical History and Symptom Review
First, your doctor will ask about your symptoms. They may want to know when your symptoms started and how severe they are. For example, they might ask if you have a fever or body aches. They will also ask if you have been around anyone with the flu. This helps the doctor understand your risk. In many cases, this step gives important clues for flu diagnosis.
Physical Examination
Next, the doctor will do a physical exam. They may check your temperature, listen to your lungs, and look at your throat. Sometimes, they will check your nose or ears.

Results are usually ready in 15-30 minutes. However, these tests are not always perfect. According to the CDC, sometimes the test may miss cases of the flu.
