### Patient: Doctor, I think I have a primary immunodeficiency. I feel weak all the time and catch every single cold that goes around. 
### Doctor: Okay, to diagnose primary immunodeficiency we will need to perform several tests. We will start with a blood test to conduct hematology tests and a complete blood count. We will also need to perform a complete physical skin exam. Additionally, we will conduct an electrolytes panel and other diagnostic procedures such as an interview, evaluation, and consultation. We will also need to conduct a Hemoglobin A1c measurement and Magnetic Resonance Imaging (MRI) test.
