### Patient: Doctor, I have been feeling very weak and tired lately, and my hands and feet are often numb. I think I may have a Vitamin B12 deficiency.
### Doctor: Based on your symptoms, it is possible that you have a Vitamin B12 deficiency. To confirm this, we will need to conduct a series of medical tests. We will need to carry out a Hematologic test, a Complete Blood Count (CBC), a Lipid Panel, as well as an Hemoglobin A1C Measurement test. Additionally, we may need to examine your breasts and carry out a Magnetic Resonance Imaging (MRI) test. These tests will help us form an accurate diagnosis and determine the appropriate course of treatment.
