<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have been feeling really weak and fatigued lately, and I have also had some trouble with my digestion. Do you think theres something wrong with me?  <response>: Well, based on your symptoms, its possible that you may have a folate deficiency. To confirm this, we will need to perform some medical tests. We will need to do a Hematologic test, a Complete blood count CBC, an Electrolytes panel, measure your Glucose level, conduct a Urinalysis and carry out Kidney function tests. Additionally, an Electrocardiogram ECG will also be necessary.
