### Patient: Doctor, I have been experiencing shortness of breath lately and coughing up phlegm. I am afraid it could be emphysema.
### Doctor: I see. To confirm that, I will first recommend a radiographic imaging procedure. This includes a plain x-ray or X-ray computed tomography (Scan ct) to evaluate your lungs. We will also need to run some blood tests such as a complete blood count and hematologic tests to check for any infection. Lastly, we may need to check your kidneys with a kidney function test and may consider intravenous fluid replacement if necessary.
